"SAS 4 version 1.11.1 has many problems.

It has been 10 months since Faction Wars was released and it is still having problems.
Many players are seeing errors where factions are full and cannot join.
faction war is full

Several players have reported problems with save data disappearing.
It is very unfortunate that all the hard work you have put in is now gone.
Data Deleted

There is an asynchronous bug that prevents players from sharing information about zombie kills.
Other players may still be fighting and dying even though there are no zombies on the screen.
Fix async bug, devs!
In addition, zombies may teleport.

Five or more players may be in one mission. Usually up to four.
After that fifth player, the players just flash their guns as if they fired them and don't move at all, and they don't die when attacked by zombies.
bug 5 player XD

The speed of the mission progress may slow down.
I have seen the speed drop to 3/4 of the normal speed.
The cause could be that some players have slow networks or mobile versions of this game.
The movement speed is slow

Your keyboard may not work if you use a non-English keyboard layout.
You can remedy this by using Alt+Shift, but many people are having trouble because they don't know how to remedy this.
I have problem. Im stuck.

The achievement "Zero Casualties" cannot be unlocked.
Some players may have set a goal to unlock all achievements.
However, they are not able to achieve it.
Has anyone unlocked Archievements "Zero Casualties"?

Ninja Kiwi, developer of SAS4, is aware of some issues.
They are urged to fix these issues as soon as possible.
