So if you have Lost Cities and are using the Space profile which adds biomes encased in glass domes as the only world gen you get a funny interaction with this mod:

Summoning the salesperson gets you the counter but the villager gets stuck up on the top of the dome. This is most likely because the mod drops the salesperson from the sky limit and since there is glass, they hit the glass and not the ground.

Not sure if there is a fix for this, but thought you might like to know, in case someone thinks the salesperson just doesn't show up.

Closing for information sake. You can reopen if you have some sort of fix.
