ugh Itch is being weird. I am checking the hash of the zip it is sending me and it is identical. I can see the update but it takes me to the same download page with the same file. I'm going to assume it will send the right file when I come back to it after a bit.
I've just tried downloading v1.1.1 and my antivirus software is still flagging the .exe file as a virus
"Celeste64-v1.1.1-Windows-x64.zip tried to load a malicious resource detected as Gen:Variant.Ser.Tedy.6023 and was blocked" is the message it has given me
