I was able to trace the bug back to a clash between my mod big-data-string and this mod.
My mod uses items to lift data from the data phase into the control phase inside localised_description, which your mod extends.
Could you please add an exception for items where name starts with "big-data-"?
That should fix the problem once and for all in my eyes :)
Heya,
It seems that, either this hasn't been fixed yet, as my play-through resumed working correctly after removing this mod from it - or there's moar bug.
Is this bug really truly squashed and splattered?
If it is, then we've got another one :)
