There's one major flaw that needs to be addressed with Bagger, that being his achievement is now no longer possible since the new flashlight slot. So how about this, remove the flashlight slot for Bagger and give back his old 3rd item slot and you can unlock the 4th slot.
Honestly, the flashlight slot also feels unneeded and i keep getting thrown off by having my 1st slot being a permanent light only slot and I have to remember to press 2 and 3 to get to my actual items. So that might go in my opinion, I get light is important but it's very odd to just have a exclusive item slot for the flashlight/lamp.
