Seeking some help I changed something don't know what

I print complex multi surface models in vase mode.
in order to have structural integrity I use some tricks. to connect multiple faces I put "slits" through the model so the tool path is unbroken to retain vase mode. I also add "ribs" same as the slit but not all the way through just enough to "touch" the other face without breaking it (again keeping a single tool path so vase mode works)
sometimes a particular printer just "won't work" the slit does not "fuse" as once piece (Its a 0.02mm slit)
I just had a printer that worked fine STOP working. the slit was not fused I could put force on it and "break" the slit.
while a proper print you can DESTROY the part and not cause that slit to fail.
I thought something changed. bowden tube used up clog something. but it seemed. fine. I tried raising the extrusion 10% still no fusion. then I saw the little SD card I had swapped out. IT had the "old" copy of the file (I added launch lugs to the latest iteration)
so on a lark I printed the old version and it printed PERFECTLY. zero issues good fusion
SO something in my slicer settings "changed" from that iteration to this iteration. I have both Gcode but NOT both factory. I save one factory as I iterate.
can anyone look at these and gain any clue "what changed" I looked at the same POINT in the gcode and I can't see a difference. I can't figure out why one works and the other does not (same roll of filament same printer)
Gcode too large had to zip it up.
When I print the old file its almost under extruded (angled surfaces sometimes have wee gaps) but the slits and ribs are SOLID fused you can see an ever so slight bulge where the filament paths bumped into itself (good that gets fusion) but on the new one the print is actually more solid (no gaps) but the slits and RIBS appear as if they are just every so slightly larger. you can see the path angled into the slip ever so slightly and there is no fusion "bump"/"bulge" ie not good fusion. which seems strange. more solid but poorer fusion? I tried slowing down I tried raising extrusion no impact. its like the slicer "adjusted" the gap somehow ??? (horizontal comp is off!!)
since old gcode works I MUST have changed something and don't realize it... any ideas at all?
