I would say go ahead and disable the residual heat for future releases. As far as the server goes, it's probably crashing from trying to remove all the residual heat "blocks" on server startup, from what i've read it's pretty resource intensive. I would say bring the server map into a world editing program and manually delete all the residual heat blocks.
Thanks I will go ahead and remove it for the next version then.
I actually did remove the heat blocks in SP and uploaded it back onto the server but still had alot of crashes and other issues
