So I haven't been able to play WynnCraft in a few years because of this glitch or bug. I haven't been able to find a definite answer to my question, I've tried searching on the WynnCraft forums only to find solutions I've already tried. I've tried uninstalling optifine, which made it work but it was extremely laggy with low FPS and it was basically unplayable. I've tried deleting legacy and reinstalling the resource pack, nothing. I've tried renaming the legacy file to .zip and that didn't work. At this point I think my graphic card is obsolete or something. I use 1.12.2 also. Would be very nice if someone could finally solve this problem I've had since 2017, I wanna return to WynnCraft, would very much appreciate the help.
