Can't pickup multiple keycards

[Night2078]

Hello everyone!

Me and my brother are in the works to set up a nice coop server. But we're running into a few issues here.

The biggest and probably game breaking issue is, you just can't pickup more than one keycard per character. The weird thing is, if you change your character via LUA command, you can pick another card up.

Example:
You walk over a dropped green key card and get it. Now you advance in the mission and are about to get the yellow keycard. BUT, you can't pickup the yellow card. Unless you buy a new character, for example i'd type "!ultimate havoc", you get a new character and you can now pickup the yellow keycard and keep the green. But in order to pick up the red, you'll have to buy another character again.

Does anyone else run into this issue or does even know how to fix it? We even tried solving it through lua commands, like !key green and it works, but it's like you pick it up, you'll only be granted one keycard.

Kind regards,
Night2078.
