I've reported a bug and you can see it in this link:

https://plarium.com/forum/en/raid-shadow-legends/677_bug-reports/136767_resources-consumed-twice/

It is still happening, and for the frist time, the error screen appered two consecutive times on the same stage I was trying to farm!  When it finally came thru when I tried the 3rd time but then I was charged 24 energy to do a brutal stage in farmham once!!!!

Is something being done about this, the event specifically uses alot of energy and this has been happening to me and to other accounts as well alot of times!  It has come to the point that I am losing at lesat 50 energy a day, that is almost half of a full tank of energy

Please help with this issue!
