No thank you for your quick reply (and for putting out so many devlogs/updates!) This asset pack is quickly growing into something great so I'm glad to pay for it. I assumed the error msg was just the manual payment problem, but it's the first time I'm running into it myself here on itch.io so I didn't know for sure.
I had to make some changes to the itch, to prevent some buyers from asking for a refund after downloading all files, so now payments are no longer processed automatically. Now I have more work to check every day, but at least I have the security of not losing my work to someone who just wants to take advantage.
I'm glad you liked my work, this content pack will surely be the biggest one I've ever created, I've said it several times, but every time I manage to overcome myself. ^^
If you have any requests and are within my reach, please just send me.
