For me (Win 8 user), DF was working wonderfully since January-ish. However, I haven't played a good game without severe lag, invisible players (most recently Kal El), and/or being kicked out mid-game, in about two weeks. Am I the only one noticing these trend?

The invisible player behavior is disturbingly becoming more common than rare.

well, there hasn't been a single update in about a month until yesterday. So unless this is since the update yesterday, really nothing has changed in a long long time because I've been working mostly on Dogfight Elite.

Thanks for the speedy reply, Zup! Could you explain what might be happening when a player stays invisible for a long period of time while other players move as normal?

I know lag is responsible for some of it, but can it be the culprit of all of it? Or is invisibility due to intended actions? Or is it some slower connection on my end? - It does seem I'm the only one experiencing this stuff.

Murder Junkie one just invisible moments ago.

well, that's what i'm trying to figure out. The explanation is due to multithreading... which is pretty technical to explain lol
I think I fixed it on the last update but Apple and Windows 8.1 didn't get it yet. And I can't be 100% sure since multithreading stuff is pretty hard to fix with certainty.

I'm still becoming invisible as I was this morning after the apple update. I first notice that the enemy becomes invisible only to appear sporadically and when fairly close. Then I realize nobody can see me though I can still bomb and text.
Apple iPad Air.

I've been invisible a few times in the last few weeks, and had a few occasions where someone can't see everyone, but everyone else can see them. I just leave and return and like magic it's fixed.

I'm on Android, so it's not just Win 8 players

I saw you for a moment REZ then you just disappeared. Have had several games this evening with multiple player invisible. FWIW I am on an older kindle.

Finn I have noticed the same thing. The same players is usually being a nascent. Most players ask and if they are invisible they leave and come back. I think better upbringing would be more of a solution. Just my opinion.
