of the 22 reviews, only 59% are positive, the only negative ones seem to be from Russian and Chinese players whose languages are not supported
here is one of the reviews, thankfully there is an english half to it that explains what is going on:

Not Recommended
POSTED: 5 FEBRUARY
My game’s language locale is Chinese and the problem is
the dialog bars, dialogue contents, and task prompts, all items and characters related to THE DLC are shown as the data package names, for example, ‘@t29672_s61219_0_ui’ is shown as the contents of a conversation, please fix it. Best wishes for a Happy Chinese New Year to the members of Warhorse Studio!
在语言环境为中文情况下，对话栏、对话以及任务提示和涉及该dlc的所有物品和人物全部为数据包名称，例如@t29672_s61219_0_ui，请官方尽快修复，辛苦了，祝战马工作室全体成员中国新年快乐！"
