As of this recent update, Starbound has been added to the list of 'compatible' games for the Mac that now crash while starting up. I shall now add Starbound to this bin that consists of garrysmod, insurgency, and just about every other fun game I enjoy on Steam. Sooooo probably not gonna be on the server for awhile D;
Yes. Item spawning mods often break during new updates because they attempt to list new items they don't have parameters for (or something). Just have to wait for a fix.
It seems this update actually removed quite a few items that ILC had colour options for and such. Just wait for Narks to sort it out, I'd do it myself but I can't be bothered.
