I don't know... It happened again during last weekend.
I had the Led panel divided into 60 modules. Some videos were ready prepared to fit modules, no matter what was their custom physical layout, I could display one single image per module, using one single slice.
The gig started with no issues and everything was looking good.
After a few hours, suddenly I look at the led panel and it is no longer mapped. Everything seems to be Ok in Resolume, but no matter what, I am unable to visual fix/map the main image back to fit the modules again and it looks all scrambled, misplaced.
I don't know what happened, I cannot recreate it so far.
It only got fixed after restarting Resolume and then moving the slice back to to fit modules again (done in seconds).
