i wrote a fictional mission , with a factory in bayern Alps.
It works well in solo mode,
but it hangs when lanching in multipayer mode ...
progressively, i supressed part of my script, and found this come from a facility tag
<Facilities>
<Facility ID="41000" Type="industrial_factory_medium1" Lat="N47*29'12" Lon="E10*42'46" IsHidden="y" Country="Germany" Points="1" Heading="0" DamagePercent="40" />
</Facilities>
i changed type, but noway ?!

Is there only stock facilities allowed in multiplayer mode ?
