Hello!
Recently I discovered in every game I make (even a new baseplate) these random errors show up in my output, making it incredibly difficult to find script errors. Here’s what I found shows up in output right after I load up a save:
It seems you have removed some components of an existing plane kit that should be there, but isn’t. The error is in one of those modules. Check the script.
Maybe it’s related to some specific plugin, if you say that it’s on an empty baseplate. Disable all plugins, then enable one at a time until you find the offending plugin.
Chances are someone has a backdoor through there. Alternatively some badly placed files.
