I tested this globaltimer problem and Vlad's fix works (like there was any doubt
).
Expanded Thief Stronghold: GlobalTimer doesn't start (like Vlad talks about here) causing endless spawning. Fixed by adding Vlad's fix "Wait(120)" to end of all blocks.
Files needed to edit in GBThfkp/Scripts are "ar0020addb01.baf", "ar0300addb01.baf", "ar0400addb01.baf", "ar0500addb01.baf", "ar0700addb01.baf", "ar0800addb01.baf", "ar0900addb01.baf" and "ar1000addb01.baf".
AR0700.BCS:
IF
!GlobalTimerNotExpired("TSPickAR0700","AR0700")
TimeGT(8 )
TimeLT(16)
THEN
RESPONSE #100
SetGlobalTimer("TSPickAR0700","AR0700",4320)
CreateCreature("TSPick3",[1919.2649],14) // Commoner
CreateCreature("TSPick2",[3557.1496],6) // Noblewoman
CreateCreature("TSPick1",[1580.2280],14) // Nobleman
CreateCreature("TSPick2",[4444.2720],6) // Noblewoman
CreateCreature("TSPick4",[767.3347],14) // Commoner
Wait(120)
END
Nice highlight color for fix. 
Though i don't understand how i have this problem now, didn't have this problem in any of my previous BWPs. What has changed? 
Update:
Forgot to add link to Vlad's post.
