I also have this issue still in the 1.14.2 update. I have built my villager breeder 200 blocks away from my single player base, and built a trading hall in the opposite direction 400+ blocks away from my breeder. My breeder teleports the villagers to the nether in a holding cell then I trasnported them through the nether to the trading hall. My villagers in the trading hall are trying to connect to the workstations in the breeder and in my base causing them to lose profession tables. I havent used UME to check my village boundaries but I am sure it is the same issue as Foxy has stated on the Truly Bedrock Server. Is there an fix for this that I can do on my end? Like killing all my villagers in the breeder and trading hall then starting over?
I have recorded proof that this bug is still an issue. I have no villagers within a 250 block radius of my trading hall and this happens everytime I log out of the game and back in. Very infuriating bug.
