Logged in to day to use my bearings. Got my second complier. Then like a dummy I thought I was getting a second split… but I got a 3rd compiler instead. I’ll never use 3 compilers! Do you think I can get a refund? Sad face!
I don’t think they allow that, best you can do is hope for another unfuse event in a year and perhaps unfuse it for coins. I’m sorry for your loss. 
In a word: unlikely.
oof and rip
but it’s gone yeah, I highly doubt you can do anything about it
This is why I am near neurotic about doing anything in the game that can go wrong from saving blueprints to spending resources to market purchases, you kinda need it imo in this game
