Enemy: Shadow lua error on casts phase door, function floor

[xnd]

everything was fine then i got deluged with a new type of bug every turn in ID.
I was in the entrance of a vault. with monsters attacking from in the vault and from outside but I think the shadows outside, since they were lev 18 they may have ported there from in the vault.

log shows it every time a shadow enemy casts phase door:

Vault id 1 opens: 2 34 21 21
AI took for target 88576 shadow :: 2847 lkrjfosrhfkj 16 < 0
