I got a new PC for my birthday and I wanted to download some add-ons for Blockland, since it's pretty much naked. I got a bunch of brickpacks, one of them being the One Random Brickpack, assuming you know what that is. When I got on Blockland to enable these add-ons, I realized that the One Random Brickpack wasn't in the list, when it was clearly in my add-ons folder.
I thought it was something to do with Blockland not being able to access it, so I tried opening it myself and I got this error:
If you've had this issue and/or know how to fix it, please let me know. Thanks.
