Major Changeling Limbcritters are immune to burn damage.

[Lady Birb]

Through a combination of in-game testing and looking at existing bug reports, I have found out that the problem with changeling limbcritters is not about projectiles like I and many others suspected, but rather that they are completely immune to burn damage. I do not know how this happened or why but it should be fixed immediately, both because it makes limbcritters really overpowered and because it is pretty well-established in lore that changelings are weak to fire.
