When modding the debug can be a lifesaver. but the .txt file doesn’t display most of the file. Getting a start-up crash with the description:
Unknown bonus value:…\src\SIM_ShipHull.cpp 52
Helps to identify the error, but I’ve got no idea what the error is. I was working with my mod when this happened, so it’s probably related to that, but no idea what else it could be.
Check your hull files.
One of the Bonuses might have a spelling error.
[bonuses]
0 = INTEGRITYBOOST
1 = SPEEDBOOST
2 = POWERBOOST
3 = SHIELDBOOST
4 = ARMOURBOOST
5 = COSTBOOST
Order of boosts is not important . .
Darn! Ninja’d by someone more experienced!
Usually that means one of your hulls has a bonus that is misspelled. My own personal demon in this area is armor; since Cliff is across the pond, he quite naturally spells the bonus as ARMOURBOOST, which I mistype about 1 in 3 tries.
Only by a minute.
Great minds, AcePalarum, great minds 
Well, you have the same answer, from two Friendly Community Mod Squad members
Good luck with the bug hunt Tek0516
Seems I put ARMOR instead of ARMOUR. Being a Canadian half the time I end up using the British spelling and the other half the American version. It gets both frustrating and confusing.
