This is one that has popped up a bit in this mission, still trying to figure it out. Im guessing it doesnt like when too many artillery rounds hitting the same spot at the same time

Ive played it numerous times but only had it pop once, you can try again hoping it will work next time

Ok, Roger that. Thanks again for your work; it is such great quality, it's like leaps and bounds above even the dev's products.
Oh and the call for fire system brings back memories like you can't believe; I was an Infantry officer for 10 years in the US Army; so I'm yelling out the whole time as if I was really on the radio making a 'call for fire', to include responding back to the Field Artillery support center's radio reports of 'shot over' and 'splash over' with 'shot out' and 'splash out'. Just like we were taught to do. It's just great fun.

Haha cheers glad you like it, I wouldve gone into more detail for firemissions but that wouldve confused the hell out of people

I've had the same issue populate each time I've attempted the mission. I do use fires quite a bit as well.

It seems that it is related to too many functions being conducted at one time; I found that by exiting Steam and restarting fresh completely, stopped this from happening. It must be excess data being held in the cache or something, resulting in not enough memory to keep running when a large amount of functions are required (like when Old Boy said too many rounds striking at once - all those actions the program must calculate simultaneously regarding damage inflicted calculations, terrain damage, etc).
