Christmas tree from Seasons keeps catching on fire every time

This keeps happening to me every time I light the tree. It's happened now six times in a row. The first time it happened I thought it was funny. Later it started to annoy me, because it ruins the holiday, everyone will be on a bad mood for the rest of the day.
It happened the first three times with my Sim families while celebrating Winterfest (on three different saves). Last night I tested lighting the Christmas tree with three different premade families and it caught on fire again on every family.

Does this happen to anyone else now? Has anyone been able to light the tree succesfully recently? Is it maybe a new bug?
Maybe it's just bad luck that I got all those fires. It certainly didn't happen this frequently when Seasons came out.
