What does this mean?
>Reject Overflow
https://doomwiki.org/wiki/Reject
>If the REJECT lump for a map is smaller than ceiling(s^2/8), then some of the line-of-sight lookups will be missing. Doom does no bounds checking on the lookup, so if the player and a monster are in sectors that are not in the table, whatever happens to be in memory after the end of the table will be used as a reject value. For demo compatibility, Chocolate Doom and PrBoom plus attempt to emulate this behavior on small overflows by predicting what would be in memory after the REJECT lump, but it is nearly impossible to do on larger overflows, and many demos on maps with very short reject tables would desync even in vanilla Doom. Most source ports replace out of bounds REJECT lookups with 0, requiring an expensive line-of-sight check in every case of overflow.
