A particular villager I have in my SP hardcore world refuses to open its trading inventory. It simply opens upon right clicking then immediately closes the next frame. I have checked the log file in logs/latest.log but there is no exception being thrown.

The video of this + the world is attached. The exact coordinates to the bugged villager are: X 286.7, Y 72, Z 242 in the overworld.

Note: this villager worked fine in 1.14.2.
