Domanda Hud issue

I am on a single sim in osg and since the latest maintence down time my Hud does not respone when clicking on it to do any. The exchange and other times is ok..  i can teleport a 3x3 region in same group anfd the Hud works. What can be the issue? I asked my host to restart the sim but he seems to be AFK since yesterday 

Odd - my first thought was that the region is still set to use XEngine but then not sure why other things would work (OSGrid has now removed XEngine)

Other thought was that perhaps something is broken in the HUD due to all the asset stuff OS Grid is doing - can try deleting the HUD and picking up a new one and see if that works.

but why would it work on my 3x3 region and not the single region

got a new HUD no change does not work on single sim but does work in 3x3 region in same group.

Not sure if the region size has anything to do with it but each region can be set with its own OpenSim.ini file so one could be set differently to the other?
