Villagers attempting to pathfind through walls

[luddebjorken]

Expected behavior

• Villagers pathfind correctly to beds and workstations according to their schedule, going through doors to get into houses.

Observed/Actual behavior

• Villagers attempt to access bed/workstation through the wall instead of walking inside the building, if the bed/workstation is close enough to a wall

Steps/models to reproduce

• Construct a small box/house with an opening on one end
• Place bed inside the box adjacent to one of it's walls opposite the opening
• Spawn villager outside the wall on the side with the bed
• Set time to night
• Observe villager pathing

Might not replicate 100%. Making walls >4 blocks thick sometimes fixes the issue.

Tested same world on vanilla server with no issues.

This seems to be a vanilla issue, https://bugs.mojang.com/browse/MC-160582.
I can also reproduce the villager using the bed through a 1 block thick wall, just like in the vanilla issue.

Unsure if it makes sense to fix this on Paper, messing with mob AI usually upsets the people who expect some level of vanilla parity. Although a config option might work here.
