It happens when you update/get a new Add-On through RtB, just exit then start up Blockland and it will be gone.If you updated something, notice that it is not there until you restart Blockland.
I was looking threw My Mods when I saw this odd thingAny ideas?Partially Off Topic: Sorry about the Taco part, im hungry :P
lol, i have the same thing and i have NO loving IDEA WHAT IT IS
Ah so thats what's causing it. Yeah I was testing an idea for something which failed and I left the code in the RTB 2.02 codebase accidentally before I deployed it, so oops. RTB 2.03 (a small bugpatch which is available when you have v11) will fix that.
