While it's common in general, I wonder how much the toxic fan reaction to the expansions could have driven "just forget it" approach to storing it.
For reference, HoMM3 expansions were to reintroduce the wider aspects of Might & Magic world back to HoMM (as the series before essentially dealt with small skirmishes little related to the main storyline). Thing is, despite the name, Might & Magic is ... science-fiction more than normal epic fantasy. And a lot of HoMM fans were unaware of the fact, and there was a bit of toxic reaction when the high-tech aspects were shown in previews.
