One sector in an underwater area of KDIZD Z1M3 got tagged with an incorrect Transfer_Heights effect which caused render glitches in that area.
There were also a few AddSectorTag calls without first clearing the sector's tags leading to potentially undefined behavior.

Thanks to the lazy counter it used in its stat display I never noticed that the serializer was incomplete and that UnlinkFromMap did not call its super method.
After changing the counter to be actively counting on each call, all the other issues became immediately apparent.
The interpolator had been changed long ago to use proper GC tracking, so interpolations only can get collected if they had been fully orphaned.
This comment was the main reason why the design flaw in this code never got fixed until recently.
It seems there can be rare conditions where an interpolation is 'lost' and later garbage collected. If that happens after the owning map is gone, all pointers in the interpolation object will be invalid and Destroy would crash while trying to unlink it. So anything that explicitly deletes an interpolation now has to manually unlink it from the map first so that OnDestroy can be kept clean of map references.
Now all this content can be localized. However, since this is actual game content it was placed in a secondary file in zd_extra.pk3, so that it won't affect the GPL-compatible status of the main one.

The software renderer does not have any safeguards against such a mapping and crashes on it.
This code was a quick hack from ancient times from when ZDoom did not have robust texture management and some recent changes ran afoul of this very special exception.
The text file
gzdoom/wadsrc/static/zscript/statscreen/statscreen.txt
is set to use strings called “$ENTERING” and “$FINISHED”, located in the language files, in intermission screens between levels in Heretic. However, these strings are named incorrectly in the language files, instead being written as “$WI_ENTERING” and “$WI_FINISHED” for some reason I’m unaware of. After renaming the original script, the ingame text shows up through what is written in the language files, as intended.
On a miscellaneous note: in GZDoom, the text between levels in Heretic says “Entering:”. In the DOS version, it says “Now entering:”. This is accurately reflected in the English language file, though, and thus faithful to the original when displayed ingame.
