There is an error in the sum of War rating in Battle #7 of season 49.
This capture is from Battle #6

We started Battle #6 with 2152, then after winning the battle, we added +49. We ended up with 2201.
In the next battle, #7, we should have started with 2201. After winning, we added +57, so we should have ended with 2258.
However, as seen in the screenshot, winning Battle #7 with the addition of +57 resulted in 2211.

This means that in Battle #8, instead of starting with 2258, we started with 2211. After winning Battle #8, we added +58, which resulted in 2269. But the final sum should have been 2316.

Here is the proof video of the last 3 battles of Season 49 of Alliance War.
