Minecolonies version
version 1.16.5 / 1.0.352-BETA

JourneyMap version
version 1.16.5 / 5.8.0beta10

Expected behavior
JourneyMap should display colonists, pets, or villagers, it does not matter.

Actual behavior
All colonies seems empty on the map.

Can we get client logs?

Have you made sure you turned all sorts of entities on on the map?

This is a journeymap bug, will be fixed in beta11. Honestly, this has been an issue for a while, not sure how it has not been reported.
This has nothing to do with minecolonies.

This problem was not present in the version just before this one:

Minecolonies version
version 1.16.5 / 1.0.311-BETA

JourneyMap version
version 1.16.5 / 1.16.5-5.8.0beta4

Here is a screenshot of both the Local Fullscreen Map settings (you can see that all entities are selected).

I did notice that in the Server Admin Global Properties, that Animal/Villager/Hostile entity Radar is turned off. Would this have a impact on the Full Screen Map?

Like I said this will be fixed in beta11 when it is released. This issue can be closed since it is not a minecolonies issue.

Your server has them disabled, but there was also a bug with them not displaying anyways. Which is fixed in our internal builds.

Thank you for being on top of this @mysticdrew. Much appreciated.
