Hi Mikhail, the error on the custom-built OSE version high likely comes from two revision checks we have in our code, specifically in DevHDA.cpp / hdaLoadExec():
if (SSMR3HandleRevision(pSSM) >= 116273) As the OSE version has a different SVN revision than our official versions, this code path won't be taken and therefore the loading fails. I'll see if I somehow can work around this.
