Hey there!
There seems to be an bug with instant flying. When you are morphed and you wear Chestplate from Modular Powersuits with Parachute and Glider installed, and you'll switch to third person move, you can permanently fly. I'm posting it here because this mod is still being updated and it looks like bug on your side. Using attached verison of Modular Powersuits and Metamorph v1.1.4.
I'll try it on the latest version, but I think this won't fix the bug at all.

Thanks,
Jason505

Yeah, test the bug with 1.1.6, but, also, does it matter what kind of morph do you use when using that chestplate thing? Or it happens only with specific morphs?

Well, after running newest version it seems to be fixed. I should test the latest version before posting reports here...
Anyway, thanks for quick response.
PS: Didn't matter what kind of morph I use.
