PPCs do heat damage now?
Yes, they transfer heat.
They were originally intended to ages ago. The line of code sat there in the xmls and never worked all this time.
For some reason which only jesus himself knows, this hotfix activated that line of code and so now they're doing tons of unintended heat transfer.
At this point I'm not sure if its worth hotfixing for two reasons:
1. Making yet another installer and informing everyone again.
2. At this point we're more concerned about more things mysteriously breaking with more small patches.
For the average game it probably wont be a problem.
Organized play its going to be exploitable though.
