Doom Builder Malfunction

[mArt1And00m3r11339]

I am currently playtesting a level the size of the Okuplok level that I designed. I am having a difficulty where if I move to 1 side of the room, I get pushed back and get slashed by an imp and die when in fact it is not in there. I am using ZDoom.

I had similar problems with my most recent map. It turns out that you need to keep the X and Y of your map within + and - 16k, or else this error can happen.

Sounds reasonable.
