I found an issue with the MK 12 Chassis-Served Support Weapon, from the Worden license; due to an issue with the LCP and the way COMP/CON handles type casting, the 2 heat it applies actually becomes 20 during gameplay.
This is due to an issue with the way CC handles type casting, because the way your LCP lists the heat value causes it to be a string, rather than an integer.
I've informed the CC devs of this, and they are investigating it internally, but in order to fix your LCP, the value of any "tg_heat_self" tag needs to have quotes removed, in order for CC to treat it as an integer instead of a string.
Basically, you need to change this:
{"id": "tg_heat_self", "val": "1"}
to this, on any such line where it exists:
{"id": "tg_heat_self", "val": 1}
Hope this helps!
