I am just trying out Spine for Linux running on a VMWare Fusion VM with Ubuntu 16.04 (64 bit) and all seems good but I constantly need to redownload the specific version I want (3.1.08) on launch (launcher is 3.4.04). I see the download required message with a large negative number implying someone overflowed somewhere...here is the spine.log - any advice?
Also, my ~/.spine/updates contains both 3.1.08 and 3.4.02 files prior to each launch.
Spine Launcher 3.4.04
Linux amd64 4.4.0-36-generic
Java 1.7.0_80 Esoteric Software
64-bit Server VM
Download required. (-4611686018427385854)
Downloading: Spine 3.1.08
Update complete.
Spine 3.1.08 Professional, LWJGL
