I found the save files but im not sure how to send it, they are DAT files . I bought the game im not playing the demo and i didnt change any of the settings
V/R Jaga
That's the file, but please send the entire folder "Goblin Burrow Manager" as unity creates log files in it with more details that could come in handy.
As for sending them, I can recommend the https://wetransfer.com website where you can input my support email happypillowhelp@gmail.com or if you have a discord account then you can join the channel here: https://discord.gg/zqEJKBmZ and send it to me in priv message.
Thank you
Edit: Or just send as email attachment, I completely forgot that they can do that xD
