Before posting yet another thread asking about the so-called infinite load screen issue, please see the Troubleshooting FAQ on our wiki here:

We have built some additional fail safes into the the next release which should hopefully give some better feedback when this error occurs.

This is typically caused by one of the following:

1. Modules are not synced correctly. Ensure ALiVE modules are properly synced (F5) in the editor and not Grouped (F2). The editor loves to group modules so always double check.

2. The Virtual AI Commander (OPCOM) cannot find any groups in the addon faction config. Check that the AI Commander has at least one Placement module with the same faction in the override box, the classname is spelt correctly and the addon is in the list of Supported Factions.

3. The Virtual AI Commander (OPCOM) cannot find any objectives on the map or within the TAOR. Try expanding the TAOR and use debug on the Placement modules to check some objectives show. Check that the map is in the list of Supported Maps. Note that sometimes maps are updated and the indexing is out of date.

4. Troubleshooting: if in doubt, always test with vanilla factions (e.g. OPF_F and BLU_F) and ideally a vanilla map (e.g. Altis) to rule out any issues with your ALiVE installation or setup.
