Yes just access the beta branch. When it asks for the password just leave it blank. No idea why it does that.
Found it, thanks.
Aside from a few IK glitches here and there, the significant bug I've encountered so far was predators when charging are failing to engage moving targets, it seems pretty persistent on every build I tried.
another one would be that mons pretty oftenly not affected by the pink spore, and when they do, will sometimes have the same issue - failing to initiate moving targets.
