Yes it does, I’ve found out the hard way :handgestures-thumbdown:
I always keep my lowans in the freezer now and it lasts for ages/even ever maybe

One cup of water with one teaspoon of sugar add yeast then stir and wait for 15 minutes. After 15 minutes you should see foam and bubbles if no foam or bubbles then yeast is dead.

Warm water, if it’s too cold you won’t see foam
