Not sure what is causing it but neither I nor any of my players are able to use scaffolding as they were intended. I can build them, place them, stack them, reinforce them but i am unable to CLIMB them. I dont crash when i attempt to so i dont have an error report but here:
MC: 1.3.2
Forge: 4.1.2.265
mods: i have a few but nothing is conflicting
