After having had trouble applying `TranslationTransform` to a simple region like so RegionPlot[TransformedRegion[Rectangle[],TranslationTransform[{2,0}]]] I tried to find my error by researching *Mathematica's* online documentation, specifically ref/TransformedRegion. After having failed to find a glitch in my code, I just did an "Evaluate Notebook" from the "Evaluation" menu, with a discouraging result: 1. Error messages like `RegionPlot::invplotreg`, `RegionPlot::nnregion`, `RegionDistance::regp` and more. 2. Different `RegionPlot`-outputs, which, as comments showed, are due to wrong `PlotRange` (so, there is a workaround for this by manually changing that option). **My question is:** Is my 10.0.2.0 installation damaged or might this be a problem with *Mathematica* itself? I have the same results on two machines (Windows 7 and Windows 8.1, both 64bit).
