I would agree, and I have looked into that (I gave the vm 6 gb, no luck, freecam still stalled), if it weren't for the fact that removing Wurst entirely resolves the issue, either Wurst is doing something intensive, or causes an intensive conflict with another mod (or another mod does with it). Also, given that it appears to be whenever certain events are triggered, they seem connected, not random, (they all involve for example, seeing the skin of the player)
