Delirium quest BRICKED - can't get to 100% delirious - FIXED

Even running 6-mod maps with 3 4-mod tablets (including a Delirium one) doing all content in the map, I never get further than 65%, sometimes even just 30%. And I seem to lose 20-30% when starting a new map. So despite doing the maximum I can, I often even regress... I almost ran out of delirium maps now in that starting area... this is really frustrating; if I'm not using the right approach, the game could do a lot better at explaining what we're supposed to do...

Or will I be able to access it automatically once I've completed all of the maps with delirium in the starting area?

Was fixed in the mean time, no longer decreases between maps.
