I can confirm this issue. As a result, the artillery fire module does not work properly for mortars in Ares Mod - Achilles Expansion (see Github).
Note that the current category "Firing from Vehicles" is not appropriate and should be changed.
In addition, the title is also misleading as the command just does not work properly for multiple rounds.

Hi BISWizard,
thank you for the reply. Also an interesting aspect is that all folders contain the files of the most recent update, even if the folder name is refering to an far older version.

I can confirm that this issue is fixed by now. The topic can be closed.

This issue is not general for Zeus. In fact I only observed it in the official Zeus Game Master missions since update 1.62. For whatever reason compositions and most empty objects are no longer available for curators there, which is a severe issue!

Update: I probably found the error.
BIS_fnc_configPath cannot convert strings such as "bin\config.bin/cfgWaypoints/A3/Land" to type config.

Thank you for the notification.
