Villagers do not work in rain. However, fishermen should work in rain because rain is better for fishing and rain increases fishing rates for players. Moreover, in the villager_v2.json entity file there is a separate set of scheduling groups and events for fishermen. However, the fishermen groups are identical to the general villager groups, so this looks like a mistake. My guess is that “can_work_in_rain”: false should be “can_work_in_rain”: true within "work_schedule_fisher".

Steps to reproduce

1. Set time to day.
2. Set weather to rain.
3. Place a bed and barrel.
4. Spawn a villager.

Expected result

Fisherman works.

Actual result

Fisherman does not work.
