2. crash

Expected behavior

its expected of the object to be pulled in by the gravity gun and not crash the game

Additional context

it looks like the recent addition from 02e232b is to blame for this issue as the dynamic cast fails on this line specifically it doesn't matter what object it is it always fails to cast and a breakpoint get hit on the dynamic cast line you can check the call stack for more issues

NOTE: I compile the mapabse source code with the latest VS2022 V143 build tools
