Error whilst running either on a saved game or newly created one.

Error while running event BeltUpgrader::on_tick (ID 0)
Unknown item name: fast-factory-inlet
stack traceback:
BeltUpgrader/control.lua:351: in function 'creep'
BeltUpgrader/control.lua:113: in function 'checkRoboports'
BeltUpgrader/control.lua:509: in function <BeltUpgrader/control.lua:504>

I am running with a lot of mods but it does just seem like a mistaken reference to an item.
I'll be trying to fix this myself but there's no guarantee it'll happen.
If I get it working I'll update this post with the changes as it might give some insight as to what happened??

Kind Regards
Mathew

Just an FYI, I am running the latest version of the mod with the fix for factorissimo and no I do not have that mod installed.

I noticed there was another thread similar to this so I'll try the original code posted in that.
