TL;DR: If you leave multiple matches in progress, any extra RP beyond the RP needed to research the current module is wasted due to a bug.
This affects Air RB the most since matches are long and you only have 1 life. So leaving in-progress matches is common.
I made a post back in June discussing this, How to avoid losing modification RP when playing ARB?
I opened a bug 4 months ago and it hasn’t been acknowledged.
Is there a better/acknowledged bug out there that I can go upvote? I’m having good matches but all the modification RP is being deleted. Really sucks.
