First of all, thanks a bunch for your contributioin to the modding community! Being able to create Mechs from scratch but not mod and fine tune them seems not logical at all, this should've been vanilla!

Now to the issue: any bills for low level modifications seems to vanish from the bill list after a few minutes. Advanced and Archite bills are fine, but low level ones just can't stick around. I tried with different workbenches too. As there are no erros in the log that seem to relate to this, and I am using other mods like 'Better Workbench Management', 'Do Until Filter' and 'Dubs Mint Menus' I can't be sure that the bugis from this mod. But one thing for sure : no other bills from other mods in any other workbench disappear like described.

Any help would be appreciated!
