Looks like a Cog issue, I was able to reproduce it: When I download "PharoCore-1.2.zip" from https://pharo-ic.lille.inria.fr/hudson/job/Pharo%20Core%201.2/126/ (which is a Pharo 1.2 Core #12303 image) and I directly start the image with the latest Win32 Cog VM from Eliot then I'm not able to go through update #12304 via the update mechanism as I already wrote in [1]. I get this error: => ClassBuilder(Object)>>doesNotUnderstand: #reshapeClass:toSuper: When I use the standard VM I'm able to update correctly to the latest version pharo core 1.2 #12307 Maybe Eliot is able to reproduce and fix it. Until then I switch to standard VM.
