Is there anywhere I can read a description of the earthquake bug?
A small clarification regarding the effect of the earthquake bug on phoenixes.
A stack of phoenixes killed by this bug can be resurrected (even in the gates, where, according to Fizmig, no resurrection is possible). But only if there are unkilled towers in the city at the beginning of the next turn; during their turn, the phoenixes are resurrected. At the same time, the defender should not have the artillery skill; otherwise, automatic resurrection does not occur.
The resurrected phoenixes can be killed by an earthquake again, but this killed stack can then be resurrected with regular spells.

We discussed options for luring enemies into the water and burying the shore so they couldn't get out, but I think it's impossible to do. And it's pointless, because you can only get stuck on this map and won't be able to continue the game. I tried staying on the starting map, running from castle to castle, even buying a couple of archers, but I still can't kill the computer.
This Walkthrough is possible; I played it this way.
Another clarification regarding the effect of the bug on phoenixes. If the phoenixes are cloned before dying from the bug, then after the clone is killed, they are resurrected regardless of the presence of artillery, towers, and the number of turns since they died from the bug.
upd
It turns out I lied; in reality, the resurrection of phoenixes occurs after the death of any stack. Whether it's an attacking stack or a defending stack (even the last one, even the machines).

And that's not all. If the stack "killed" by the bug was incomplete at the time of death, and therefore you can cast resurrection (on undead) on it, then the stack "comes to life" after the spell and you can play with it normally.
But if the stack "partially killed" by the bug is finished off with something, i.e., only a pile remains on the ground, then nothing can be done with this pile.
