NOTICE: This wasn't a bug, it was me being a dingus. Please clear your item defaults before doing the Canvas Trial.
This bug report applies for the Canvas Trial custom world, on version Gamma 1.4.0 of Beyond our Worlds.
I tried to place Strike Drones(as instructed by the custom world), and instead I got some really odd cores.
To recreate, place down Strike Drones and set their faction to Crimson Infected, then test the world.
(I genuinely have no goshdanged clue how or why this happened, and not even the console had anything to say about it.)
