Your English is good :)

This is a duplicate report and/or the developers are already aware of this bug/problem.

Please check the feedback tracker to see if an issue exists before creating a new one and instead vote the original one up so the developers can see it's a common problem. (Most of the most popular will be up top if ordered by Priority).

You can also use the 'Filter' textbox to search through existing reports using a keyword if it's not close to the top.

A list of important bug/issues that the developers are already aware of can also be found on the DayZ Forums:

Any additional images of the problem in question is always appreciated (if possible) and can be added by using the 'Upload File' section within a bug report.

I have added the original report above under ‘Relationships’
