Fixed for me in 1.48. Thank you

Same trouble for me. I switched from FR to ENG and no more trouble...

Yep agree with Scroll. It is really annoying to not be able to calibrate the Azimuth and elevation when mortar is not on flat ground (with gravity reference).
I did a test with stable version 1.48 and issue is still present.

I confirm that the issue is still present for version 1.48.
I tried to search for a workaround and launch a script (on server only, or clients onlye) in the "init box field" but with no success for the moment...
I hope this trouble will be solved in next release.

Same problem for us especially when it is a vehicle even if it's not equipped with ir camera
