A clear and concise description of what the bug is.

Legacy of Rust is unplayable since and including 4.12.1 but is playable in 4.11.3 on Linux arm64.

It looks like initial elevation of some raising and lowering triggered sectors is not correct, which I noticed first on map13 (since gzdoom upgrade) but the issues could be bypassed there with jumps / etc. But map14 is obviously wrong and no way to progress.

Correct presentation of map14 in 4.11.3:

Room floor already bottomed out, floor under bald cyberdemon raised with 4.12.1 - 4.14.0:

Steps to reproduce the behaviour.

1. Install gzdoom_4.14.0_arm64.deb from Releases.
2. gzdoom -iwad doom2.wad -file id1.wad +map map14
3. Run for about 10 seconds in a straightforward manner.
