Does anyone else have issues with simplify3d make jacked up print moves and ruining

Does anyone else have issues with simplify3d make jacked up print moves and ruining the last layers of the print? It is not cool…

Can you show an example of what this looks like?

Just dose a random circle and a blob starts doing it last few layers but anything else prints just fine. No layer issues no over extruding. Just decides to do a random pattern with a blob. I printed same part in matter control and the layers were not as clean but no crazy circle blob crapmissing/deleted image from Google+

Figured it out I changed the infill from concentric to rectilinear and no issues. The concentric fill just starts doing random stuff and throws my Pinter into crap mode lol.
