Hello! Want to get 5000 points on [GlobalMasters](http://globalmasters.intersystems.com/)? I'm launching a bug bounty for a bug with which I've been struggling for the last 4 years. Have tried to resolve it many times, but no  dice - can't track it down. [Here's the issue](http://github.com/MakarovS96/cache-tort-git/issues/4). To claim this bounty you need to: 1. Create a pull request with the code to fix the issue outlined [here](https://github.com/MakarovS96/cache-tort-git/issues/4). 2. In the pull request _OR_ in the issue _OR_ in the commit message describe what's the reason for this bug and how your change fixes it. First come first serve. Bounty would be paid only **ONCE** for a first working solution. [Challenge details are here](https://globalmasters.intersystems.com/challenges/2580). **UPD**: we have a winner [here](https://github.com/MakarovS96/cache-tort-git/pull/7). I'm still testing but the fix works great so far. Please submit further bug bounty entries ONLY if you think Robert's solution does not cover some part of the issue (with rationale for that) - as I'm of a mind that it does cover everything.
