I had several armorers and smiths with really good armor/weapons switch to farmers when I put down composters. Meanwhile jobless villagers never choose a profession, and just wander around aimless, even if I put a new job block in front of them. If I break an existing job block, the villager immediately switches profession while the jobless remains jobless.
All of my existing villagers with established jobs of which I regularly trade with just randomly switch if I put down new blocks instead of jobless villagers claiming them.
I've spent countless hours grinding for trade resources to upgrade their levels and get decent trades, and then they just switch jobs spontaneously. Extremely frustrating.
Same issue. I create worlds on android and even though others on same wifi can see it, when they try to join it says unable to connect to server. I had the same issue connecting to theirs ( also android and they connect to each other ok). I managed to connect to theirs once after joining a server world and quitting it but this does not help them join my worlds. Using newest version. Restarted turned wi fi off and on. Not resolved
