Hi Telric, thanks for digging in to this! I used the tester item to go to 100% sleepiness, set time to night, placed bedroll, and crouched on it. The only change in the buff list was the obvious addition of "buffcrouching". In the creative menu I saw that there are multiple bedroll IDs, the default one the modded game gives was bedrollblockvarianthelper, so i spawned a plain ol bedroll, and still did not receive the buffIsSleeping.
