Group "Slow Time Upgrade Levels" On Event 93 is the one causing the problem all your events inside this Group are referencing to "biggergaps_upgrades" for changing animation instead of referencing "slowtime_upgrades" Animation.
Another thing is that these events runt every thick
-Bigger Gaps Upgrade Levels
-God Mode Upgrade Levels
-Slow Time Upgrade Levels
-Spawn Chance Upgrade Levels
you should put them under the Triggers that you have on Group "Upgrades Menu Buttons"
Example On Touch on "biggergaps_buy"
Total coins is bigger than biggergap_Price
Bigger_gaps upgrade < 7 >>>>>>>>>>>>>>>>>>>>>>>>>>>>All your Actions here that you already have plus the ones from goup "Bigger Gaps Upgrade Levels"
And do the same for all the Group Upgrades
============================================
And I would recomend you for the Next Time to not share your whole Project because it can get stolen mate, when they ask you for a Capx project try to remove everything that you can and just leave the code related to the problem just with minimum capx enough to replicate the problem.
Another benefit of doing this is that while you deleting or recreating a minimum capx most of the Time you will find the error before you post it
And finally, I would like to say for your first project you did a great job mate keep it up, the graphics look great too, one thing I see you can do quite a lot of optimisation Though, good luck with it
