Can you help me? Solid mobs mod dosen't work correctly

[Gintas2002]

I have my own mod pack, I added this mod, and it doesn't work correctly, basically it feels like I am on a server and the server doesn't have the mod but I do. basically when I jump on the mob it kinda glitches for a bit and I fall off or cant move on it (get stuck), no crashes or anything but looking at the recent log it shows some error with this mod, and when I turn on platformMode it doesn't work at all, seems vanilla.

does it work when its just the mod by itself?, you might have to do a binary search through your mods to find the conflict
