Ensure crushed characters are fetched from the correct location

[PatrikLundell]

Summary

None

Purpose of change

Fix #77786, i.e. crushing due to explosions using the reality bubble coordinates rather than the coordinates of the explosion map.

Describe the solution

Fetch the character from the correct global coordinates rather than feeding the explosion bubble coordinates into a fetch operation that does the same conversion but using the official reality bubble as the coordinate reference.

Describe alternatives you've considered

Testing

Followed the instructions in the bug report save, verifying the issue (and locating the location where it goes wrong through the debugger).
Modified the code.
Repeated the bug report replication, seeing no reports about the PC being affected by anything.

Additional context

This is a side effect of the change to make explosions with effects at least partially outside of the reality bubble being performed in their own map. The creature tracker, however, is always assuming bubble coordinates refer to the official reality bubble, so you have to make use of the corresponding operation using absolute coordinates to get the correct result.
