Warnings after a power outage.

ram876

Hello! I had a project open with unsaved changes. The power went out. After the power was restored, the project kept opening with an error. How can this be fixed or how can I stop these errors from appearing all the time?

Spinebot

These warnings indicate that Spine found deform timelines referencing a wrong slot and automatically fixed them when loading the project. This likely happened because the power outage caused the project file to be saved in an inconsistent state (or not saved at all, leaving a corrupted backup/autosave).

Here's what's going on and how to address it:

What the warnings mean

The warnings say Fixed deform timeline (wrong slot) for the mesh left_hand_line_arm in the slot left_hand/left_hand_line_arm. The placeholder name left_hand_line_arm2 suggests that at some point the slot or attachment was renamed, and the deform timelines in several animations (idle, melee_attack_sword, walk) were still pointing to the old slot name. Spine detected this mismatch and auto-corrected it on load.

What you should do

The good news is that Spine says it fixed the issue automatically. The warnings are informational — they tell you what was corrected. To make the fixes permanent and stop seeing the warnings on every load, simply save the project after it opens. Once saved, the corrected slot references will be written to the file and the warnings should no longer appear.

Open the project (let Spine apply its automatic fixes).
Check your animations visually — especially the ones listed in the warnings (idle/idle_down, idle/idle_left, idle/idle_up, walk/walk_down, etc.) — to make sure the left_hand_line_arm mesh deforms correctly.
If everything looks good, save the project (Ctrl+S / Cmd+S).

If the project was not saved before the outage

Spine makes automatic backups before each save. You can find backup copies of your project here:

Windows: <user home folder>\Spine\backups
Mac:     <user home folder>/Library/Application Support/Spine/backups
Linux:   <user home folder>/.spine/backups

You can open these backup files to see if any of them represent a cleaner state of your project before the issue occurred.

To prevent future data loss, consider enabling auto-save in Spine's settings and using a UPS (uninterruptible power supply) for your workstation.

My project still shows this error when I open it. I just click OK every time.

The warnings are fix ups that Spine has done. Once you save the project, the next time you open it these warnings should not appear.

You cut off the top of your log, so I can't tell what Spine version this is. If it's 4.3 you can post or email the .spine file and we can take a look. contact@esotericsoftware.com

Nate Hello. My program has stopped launching. I wanted to send the warning log, but now the program is crashing. I sent the log after the crash to your address.

ram876

Nate I would like to note that if I forcefully specify version 4.3.23, the program starts.

Nate

4.3.25 is up now, should fix this!

ram876

Nate Thank you. Yes, the program is now working. But warnings still appear in my project every time I open it.

Misaki

ram876 To accurately identify the issue, I think it would be best if you could send us the actual Spine project. Please send us the project files via email, as Nate instructed: contact@esotericsoftware.com

Misaki

ram876 Thank you for sending the Spine project file. I checked it, and just as Nate pointed out, the warnings are simply Spine reporting that it has automatically corrected invalid timelines in the file. When I saved the Spine project file and reopened it, the warnings no longer appeared. So, please try saving it once.

ram876

Misaki I sent the project file and the log.

ram876

Misaki Unfortunately, the situation is repeating itself. I saved it and saved it as another project. Before that, I tried reinstalling the program.
Okay. The main thing is that the project is working.

Nate

We fixed this or a related issue in 4.3.26. It is likely to fix your problem!

The 4.3.07 launcher also has an issue we are investigating (< 4.3 versions may fail to run on Windows). You may want to update to 4.3.08 when available, soon.

You've hit the unlucky lottery for Spine problems lately. 😬 Sorry again for the trouble!

ram876

Nate Thank you very much. After the update, the warnings disappeared.
