A bug seemed to happen a few minutes ago, as Imperial reinforcements arrived in Amritsar.
It's time to go to work so I will be able to investigate only this evening... sorry

Since something wrong happened, time is sort of suspended, so no ship should be destroyed, and no fleet can move

It's lunch time for me and I have a few minutes to investigate.

It seems that, with the actual code, the battle is just to big for the server to run it correctly.
So it's a scaling issue, not the most easy to handle...

The situation has been resumed (almost...), but the issue is not fixed: it will probably happen again if a new fleet joins the battle, or maybe in other cases too.

I tried a fix, we'll see if it works if another fleet joins the battle!

The fix seems to work!

Just for your information, if ever someone is interested: each time a new fleet joins a battle, there was a portion of code doing one big operation for all the ship engaged in the battle. Obviously, 40,000 ships for one operation was too much.
So I split this big operation in several smaller (one for each slice of 10,000 ships), and it seems to have solved the issue.

Late, but thank you for finding a workaround! :) This battle certainly is enormous.

Another bug revealed by the gigantic proportions of this 14th battle of Amritsar: stats are wrong

There are 2 problems:
- the number of engaged ships should not be less that the number of lost ships (this has probably been caused by the bug at the beginning of the battle)
- this "16777215" number is more than suspicious; this is indeed the max value of the "mediumint" data type in MySQL; so the real number has exceeded the maximum capacity, I have to change it for a bigger integer data type.

Stats have been manually (and carefully) corrected :)
