I noticed on the island and in normal missions that I have been getting texture and sound issues.
First, the textures for some weapons, and zombies are just...........not there. By this i mean they are invisible, but they still function properly (the weapons do damage, and the zombies are still visible to survivors).
Second of all, I have been getting problems with gun and melee sounds. Sometimes, they are (as with the textures) not there, there is merely silence (some zombie sounds are not there as well) but will pop on occasionally and turn back off.
This happened 2 weeks ago and only once because the moment I reloaded the page, everything went back to normal. However, yesterday and today, I have been getting the issue and reloading the page is not helping anything.
Notably, this is only apparent on missions and the island, but in infected attack defense, there is no issue, all guns and zombies are visible.
I saw a previous post on invisible zombies, but I do not know whether this bug also had issues where the survivors were not attacking the zombies (because in my case, the zombies were only invisible to me, but my survivors still shot them).
