I know for sure that I use those flowers from Veranka everywherrre in my houses, because I loved them so much in TS2. So it shouldn't be them that directly caused the crash? Maybe a conflict of some sort, or just bad timing.
maybe o.o i scanned with the mod conflict detector but it didnt say any issue about them. i will try to redownload in case they got buggy for me. thankyou for letting me know :)
