Free actions cannot be performed when at 0 MP

Which they should be allowed as the actions are free. Something in the new MP comparison system now disallows actions that should be free (so don't change the used MP amount any more than before).

This is hopefully just a case of making sure that if the MP is at 0 but didn't use any more MP than before, then an action should be let through.

Less critically this also impacts the "infinite MP" cheat by requiring first to have enough MP to do something and only then is the cheat effective. If that gets fixed at the same time that would be nice, but that isn't absolutely necessary to fix at the same time.

Couldn't reproduce this by getting the MP down to 0 and moving one of the parts. Any steps to reproduce?

I can't remember if the original problem report was on the community or dev discord but someone showed where they had 0 MP and were unable to start an organelle move operation. So look for that...

Personally I've only seen the problem variant with the infinite MP cheat where I use some MP and then turn on the cheat but I'm unable to place an organelle that costs more than the left over MP.
