Well the thing is the moment shared senses is active something is triggered that causes the crash and I don't really know what as at that point there are to many variables to track from what I remember going on, so I can only try and give more details.
It might also interact with the anonimity curse now that I think about it, I believe al 3 crashes I had with shared senses also involved the one with the anonimity curse but while the first bug could be triggered by scrying one with the anonimty curse perhaps this second variant triggered the same bug but with an event happening while under shared senses.
If so then my current run can't really be used as a test case.
