megaphse.wad: why action 71 fails?

megaphse.wad
When you press linedef 3139 the sectors with tag 32 are supposed to lower but that doesn't happen in prboom-plus with -complevel 2. Why is that?

I don't know, but I fixed it by merging three pillar sectors. Cool map BTW.

Oops, I experimented with a wrong save. Now i believe it has to do with floor height below -512. Trying a test map, with floor height 0 it works, with -600 doesn't.

(^ test WAD which should prove my point)

Ohhh, now I remember... One of the strangest limitations in vanilla Doom, it just doesn't make any sense unlike visplane or seg limits. :) Yeah, you're right.

Yes, Strange indeed. This clearly wasn't tested under Doom2.exe DOS. As an aside, secret sector 284 is inaccessible.
