Seems like alot of my player base has this bug. They dont see the mod blocks, its invisible, and they see underneath it, if they step on it they et stuck, we tried alot of things to fix it but it doesnt seem to work... please fix this bug/glitch...
first picture of what they should see
Second picture, what they see

Does the other players actually have the mod installed?
Often not seeing modded blocks is due to missing the mod.
