This bug is still present with farmers.
I healed a Zombie Villager in order to have better prices.
After that I made him a farmer with the following trades:
14 wheat for 1 emerald;
16 carrots for 1 emerald;
After trading a bunch of carrots the trades became as follows:
14 wheat --> 1 emerald;
33 carrots --> 1 emerald;
The same happened yesterday with another farmer (healed), with a little difference: this time I traded a bunch of emerald for golden carrots and the first trade from 14 wheat for 1 emerald became 22 wheat for 1 emerald. After a while the trade returned to its original state.
Could this bug be related to the renaming of internal IDs made in pre5?
I tried to regen with 18w20b an old world made with 18w16a (with seed -325079803) and I've got the same problem. Some times stuck at preparing spawn area 1% and other times the message doesn't even appear.
Some times the game manage to create a crash report (which i attach on this post), but in order to close the game I need to kill it with CTRL+ALT+CANC every time.
