Unable to claim empire tiles
I've had this a few times, but it's just happened in a place that breaks a game, so it's inspired a bug-post.
Symptom - workers refuse to claim enemy tiles.
I was playing a workshop map, named The Vault (http://steamcommunity.com/profiles/76561198031969859/myworkshopfiles/?appid=230190&browsefilter=mysubscriptions&p=2)
The map has a bridge, then a chamber with lots of portcullis and traps, and empire units. This then leads into a corridor. Once I'd cleared the room out, the imps converted maybe 4/5ths of the first room, but refused to convert any of the corridor.
I used the imp rally flag, and they'd stand idle beside the empire tile.
I dropped them on the edge of the tile, and they just wandered off.
Nothing was attacking them, and they were just idle (so no higher priority tasks in the way).
It was as if the tile had been flagged as 'empire non-claimable'.
I've had this in smaller doses in other workshop maps, but not had so many tiles in one place blocked out.
I was under 25mins into the game, and it was a fresh game (not saved it & reloaded). It was also the first map I've tried to play since starting WTFO.
I'm on a 64bit machine with 16g ram on Win10.
This is version 1.3.1f5.
