Thank you for sharing your experience and I'm sorry to hear about the frustration with Merge Academy. Losing progress on a timed challenge is definitely disappointing. Overall, I think the mini games within Merge Academy should be 8-10 days, some of the generators need a lot of charging.
Regarding the compensation and the time lost during the Merge Academy issues, here in forums they are unable to assist with requests for additional compensation or days — those decisions rest solely with our Community Manager Pogo_Sconnie.
I'd recommend reaching out directly to him regarding your concerns about the 50 bolts/energy and the overall experience during that period.
Hopefully this time will pass, and we will get back to Merge again without issue. Take Care 🌺
