Eqmod alignment cleared when a new client is connected - by: pch

I have a problem with the Eqmod alignment data that are cleared when a new client is connected or an existing client send <getProperties version='1.7'/>
This is using the last version from the ppa: 0.3+r3339~201708231229~ubuntu17.04.1

To reproduce the problem :
- start indiserver indi_eqmod_telescope
- connect to real mount or the simulator
- set sync-mode to Add point on sync
- slew and sync to three stars, you see Number of point=3 triangles=1
- connect with telnet and send <getProperties version='1.7'/>
- you get an error message about AlignData.xml file not found
- slew to a new star and sync, you see Number of point=1 triangles=0

I not tested but maybe if AlignData.xml is present you can get the old alignment data ?

Any idea where to search for the problem? I am a bit lost with the alignment code.
