once again, as this seem all the same problem, to specify it more:
in my experience since weeks, it is in special when i copy a corona light (or cam, or instance , or other generator object) and then move it while ipr is on,
almost in 100% of the cases i get a crash due Corona render, and c4dfreezes (i need for force quit it).
as examples:
copy light, change value or move it-->> crash
copy camera, move it--> crash
copy instance, move it--> crash
copy in c4d we do mostly via ctrl-drag direct in editor.
it doesnt happen in small scenes, but in any realistic production normal arch scene we have here, on any PC, and seems quite reproducible.
alone today like 15 crashes so far, i really hope this gets high priority as fix
