About 50% of the time I use the Texture Unpacker function, Spine will freeze to a black and grey screen, and the texture will not be unpacked upon reopening the file. Checking the log, whenever it crashes it reports this:
java.io.FileNotFoundException: C:\Users\Jacob\Desktop\Tarnishing of Juxtia - Repos\TToJ - Resources\trunk\Character Sprites\Player\pieces\Armor\npc_lostJuxtian\legCloakRight_default.png (Access is denied)
"Access is denied" happens every time, but the file itself seems to change each time I pack the textures. The rest of the log is attached below.
