Hey there! Glad to hear you enjoyed playing through the mod despite the small headaches with the additional collectibles.
Yeah, the mindset at the time when placing the Wasp Cameras around in Donut Mod was that we wanted to make use of the areas of the vanilla maps that aren't normally used. The idea behind that was to give veterans new reasons to explore without being limited to the 7 Collector Cards (as there's no way to increase that limit at the time of this writing), while also offering more opportunities to make Coins. However, I can see how it feels a bit excessive (especially since Donut Mod 3 and 4 do not require that the player invest in any rewards to progress with the Story Missions), and it quickly turns the maps into a 'check every place' rather than feeling like a natural reward for exploring areas. The feedback is appreciated!
I'm afraid at the moment there isn't any sort of map available that shows all the current Wasp locations, but using Lucas' P3D Editor 4 they can quite easily be obtained. I can potentially grab it if you'd like.
Again, many thanks, and hope you enjoy the other mods here as well!
