I'm using a rather old (5-ish years?) HP Pavillion laptop. Running on fully up to date Firefox, and again the issue has been happening for me since Snow Wars first began (3 years ago?), so it's nothing that's started because of a recent update, or lack of one. And I haven't found it a significant enough problem to report in the past, lol. Just figured if it was being reported anyway, might as well supply all information possible XP

edit: after reading lostwords' post, I have to add that I also keep Sylestia at 80% most of the time. For playing snow wars this year I've been putting it at 50% just so I don't have to scroll all the time to place units and move throughout the game.

Sometimes happens to me too, but generally it'll pick back up if I wait. A few times I'll have to refresh though.

I use 64-bit Firefox on a Windows laptop, version 64.0.2. What Mika said--it's been occurring for a few years here too.

adding my info in here as well since ive had it happen before as well: using a 4-5 year old HP envy laptop on fully updated firefox.

(Since it occasional causes issues though, i also keep sylestia zoomed to 80%. doubt that info is needed here but figured i might include just in case)
