The instruction (guide on how to use the tool) has been updated, please pay attention and read it!
Today RUT has been tested on 5 different clean PC's:
1) Warzone was downloaded for the first time on PC, no other software was used before
2) Any spoofers / public scripts not used
3) Different versions of Windows
4) A regular RUT loader from the instruction, not a Dev version
5) Testers strictly followed the instruction for use
Result: no 1 shadow ban or any issues.
Unlocked and saved weapons, operators, vehicles / operators / weapons skins, calling cards and emblems, watches, checked all the functionality of RUT Ultimate - everything works fine and absolutely safe.
In Warzone, if some items do not saved for you - watches, operators, vehicles or something else, then the problem is in you, you are doing something wrong.
BUT, if you want to use RUT on multiple yours/someone else's/console accounts - you must use a spoofer to avoid getting a shadow ban.
If you was banned earlier due to any software (EO or something), received shadow bans and etc. on another accs - all this leaves trace files in your system, so again - you must use a spoofer to avoid getting a shadow ban.
