MT#6 game world has suffered from a background process crash a couple of times. The issue to this is known, but fix is not yet available. In the meantime I have made some measures that will prevent it hopefully.
To be able to fix it, I need to test a few different factors, and since I cannot do such large-scale testing locally (the 300000 routes etc), I am doing it while the game world runs.
Basically this means at the moment that for the next 1-2 days the route sales and history data will not be stored. All routes will fly normally, and all income is processed and money is credited. Only the normal 3-week history information is left unstored for the next days for testing purposes.
(Edit: Test completed. No real luck on the results, in regards of the issue.)
