Map 03 from dbf64 (https://www.dropbox.com/scl/fi/jm79o396abx88u1xfl9ws/DBP_64_RC3.zip?rlkey=y9m4oolf4qhrxjagaea66wppc&dl=1) doesn't load because of a missing things.h
The last working version for me was: gzdoom-x64-g4.14pre-91-g878c5f085

The VerifyBlockMap msg in the console can be ignored, that's also in the older versions.

Steps to reproduce the behaviour.

Explain how to reproduce

1. Start the game
2. open console
3. type in: map (or changemap) map03
4. Now the error msg comes up.

This could be related to the file system changes that were done last month. The latest official release (4.14.0) doesn't include those changes, so use that instead of a development build.
