PC/Steam, 1824, official pvp-server
Climbing bug. You put on Spiderclimb boots, use them for a while, then put normal armor back on. Suddenly all climbing becomes super slow and heavy stamina draining, much slower than normal climbing ever is. And it stays that way even if you put the Spiderclimb boots back on, until you log off and come back in.
