I'm afraid I have no idea, I've never seen anything like that.
That means that some other mod (Unless you've gone in to those files yourself and done something manually) has modified those files in a way that removes their chance values. -It shouldn't affect your gameplay unless some mod is also trying to spawn those bot types, though.
Load into a raid on Customs, and then go into donottouch/debug/bigmap_bosses.json and look for the entry that mentions bossBully. -Is it present, and if so, what are its BossChance, BossZone and Time settings? That should tell me a little more about what's happening.
Hey mate thanks for the reply, ok so i tested Customs and it seems fine, i think my issue is Woods and i repeated the above steps and this is what is displays:
"BossName": "bossBully",
"BossChance": 38,
"BossZone": "ZoneDormitory",
"BossPlayer": false,
"BossDifficult": "normal",
"BossEscortType": "followerBully",
"BossEscortDifficult": "normal",
"BossEscortAmount": "4",
"Time": 15
I haven't had a chance to test other boss maps as yet.
Thanks again!
