Hi-
For starters, I'm not sure if this is the right area to post, or if this is only an RTB related issue, but anyway.. A strange issue that I've encountered is as such; I will download any mod off of RTB or manually install it to my Add-Ons directory, and will be able to enable it through either the custom server options or the RTB menu- except for bricks. I can't seem to get bricks to work. I have all of my brick_##.zip in the Add-Ons folder, yet they're not coming up in the RTB menu or the Add-Ons list.
Explaining a bit better:
I'm using this brick pack as an example, I've tried it with dozens but it still doesn't do anything:

I clearly download it here. I then go to my BL Add-Ons menu and it is not visible:

However, it is present in my Add-Ons directory:

Thank you in advance.
