Simple Beds textures rotation is incorrect, causing the texture to look like this when its used with the excalibur resourcepack:

I tried making a resourcepack to override and fix the bed model (path: assets\pfm\models\block\simple_bed\oak\full\simple_bed.json)
But strangely it only overwrote the model as an item within player inventory, but not the block model when its placed.

Yeah I didn't realize the UVs were a little funky on the foot of the bed, the bed itself is split into foot, and head folders and a full model (only used for item rendering) which is what you overrode, however if you want to fix this manually before I release the next version you'll need to edit the red foot mattress as that is the parent model.
