Hi, and thanks a lot the review. Sadly, as in this case, it seems that there's a strange issue some user encounter once in a while which somehow makes History completely unusable, and even deletes the data. I know very well about it and I tried again and again to find a solution to it but I simply can't understand why it happens in the first place (without finding the actual solution it's really hard to fix it). I need to redesign the whole History saving feature and probably this issue will be solved as well. I'm really sorry that you also had this problem :( Hope that reinstalling it solved the problem in your case. Thanks for your support, even though you had problems with it. This kind of feedback gives me a lot of reasons to continue to improve the project further.
