Summary0001830: CANSEELOS through corners
DescriptionWith AdvancedLos=0
CANSEELOS through blocked corners(static, dinamic) return 1. But NPC can't do actions with this target.
With AdvancedLos activated corners is blocked for all characters(I think - the right variant).
This difference in players and NPCs rights can be used for example as way of easy killing of monsters-archers, you can shoot, archers - can't shoot.

Tested this problem again. Results:
Error is NOT connected with the char type(player, NPC), but is a problem in old(default) LOS algorithm.
Sometimes character A CAN see character B, but characted B CAN'T see character A.
The example of this is this issue - character in position: 2077 796 CAN'T see character in position 2074 800, but character in position: 2074 800 CAN see character in position 2077 796. You can simply check it with this code:

[FUNCTION TEST_LOS]
TARGETF TESTLOSF

[FUNCTION TESTLOSF]
SERV.B SRC See ARGO: <SRC.CANSEELOS <ARGO.UID>>
SERV.B ARGO See SRC: <ARGO.CANSEELOS <SRC.UID>>
RETURN 1

This problem affects all proceses connected with LOS checks: combat, magery etc.

Issue can be closed, because it is default for Ultima Online.
