1. Stop whining. If you are worried by possible rollbacks, just take a break and you will be fine.
2. If you haven't noticed it yet, I'm the only person who maintains the server and makes any updates.
3. Server machine is exactly the same one, but with different OS.
4. Trying a different OS which would significantly cut server cost is always worth a shot. This means that the server will be online for longer time and less dependant on donations. Otherwise it's just shut down some day as 2238 was. Also, remember that I'm using massive amounts of my free time to get this running and updated once in a while. DocAn is spending a lot of his free time to make rerolls to those who donated. We are not rewarded with money in any way as all donations are used to pay for the server.
5. As it was said, if the thing keeps crashing, I will use the other solution to get rid of this problem. All you need is to have some patience.
Thanks to those who understand.
