Smoke is disappearing

After the most recent patch (as of 3/26) smoke clouds just vanish on my screen shortly after deployment.

I've noticed this too. This is especially prevalent with the smoke launcher attachment, as the smoke only seems to last 3-5 seconds before it will disappear for me.

Same, smoke totally 100% broken

yup. still broken as of 5/24
