Following today's update, we are now under the impression that Valve believes rocket and demo jumping is fixed, and are unlikely to make future changes. With that, we have reverted the Tempus database to just minutes before the Gun Mettle update hit. This revert is slightly tentative, as we don't know if Valve is going to turn around again and change more things. It's also hard to 100% tell when jumping for both classes is completely back to its original state.
This obviously means times between then and now are gone. I apologise for this, but in the long-term I'm more cautious about the integrity of the database. I don't want people looking back at times and going, "but was that set when solly/demo got buffed?". That being said, the way this was handled was messy, as we haven't had to do something like this before. Without direct communication with Valve it's hard to know what steps to take, but hopefully this was the right one.
Sorry again for the lost times, but fingers-crossed this is the last of it. If not, we will try handle it a bit more smoothly.
