Subject: [PATCH] Fix Ancient IIS Module Bug (#22198)

closes #2951

Oh my god this was the oldest confirmed still active bug in the entire
issue tracker, and it's 9 years old. This bug was reported originally in
2017 and was never fixed. Uhhh. Hell.

This makes it so that pAIs can actually control a hardsuit via an
installed IIS Module. The thing that module was meant to do 9 years ago.
