Found a Skorpion on a crashed police car.
Found a mag on a diff. server, attached it and used it, it worked fine.
Used the weapon, reloaded the mag twice.
Found an East Silencer, attached it to the Skorpion.
Removed the mag from the weapon
Can't attach it anymore
Tried with a diff. mag, can't attach it either.

• Also, the weapon was stashed before it broke.
