hi, I recently updated my KSP to 1.2 along with all mods. everything seems to work fine except DOS universal storage parts.
since the update, all DOS universal storage parts seem to be unresearched. they do not appear in the VAB / SPH parts list and I cannot launch any of my old rocket designs containing these parts ("this vessel contains experimental parts which are not available at the moment"). parts that are on vessels already work correctly. my tech tree is almost fully researched (only some high tier nodes remain).
both DOS (1.3.4) and universal storage (1.2.0.1) are installed using CKAN, no newer versions are available elsewhere.
