wenwell, hi. Streams will probably be in about a month or so.
Regarding the prospects for the 4th month - I haven't planned that far ahead, but we can calculate it based on the number of snakes. The situation on day 147 looks like this: number of snakes in the castle (growth).
147: 43(23)+0(19)+0(15)
217: [43+23]*2(23)+19*2(19)+15*2(19) +27 in reserves, or 204(61)+27 in reserves
247: 204+61*3+27*4 in reserves = 387+108
311: (387+61)*2+27*5 = 896+27*5
411: (896+4*61)*2 +27*8=2280+216=2496
At the same time, what improvements can be made? 1 snake was bought on the 2nd week (this can be avoided), and one of the swamps is not in the castle on day 147, that is, 5 additional snakes in the first month give +5*2 (2nd month)*2 (3rd month)*2 (4th month) = 5*8 = 40.
The number of snakes for buying on day 411 is not that many, but if we also generate snakes in the 2nd month, then this is +15*3*4=180 additional snakes, and 15*3*2=90 snakes in the 3rd month. We get a maximum of 2806 snakes on day 411 - if I didn't make any mistakes in the calculations. Well, something should also join us.
In terms of money, it seems to be okay. 2.8k snakes cost 673k gold to buy. I assume that without snakes, we won't reach the Necropolis, which means the income will be 26k gold per day - but this is after dealing with Inferno and the Barbarians.
Even if we assume that the 2nd month will have an average income of 16k (all on Barbarian spawns + swamp, Inferno will start to generate income), and the 3rd month will have 26k, then by day 411 we will earn 1176k gold (or 500k extra) + events for money. It seems like it's enough for a buyout and to buy some minor things. Or, due to the non-instant delivery of troops, it's enough for two buyouts.
Accordingly, the question is whether there will be enough snakes for the Necropolis and the boss. How to deal with early Inferno, or rather, the garrisons at 10 gold mines, without wasting weeks on ducks in the middle of the 2nd month - this is an open question.
Among the controversial points is this strategy with animation and morale/luck - I don't even know. And again, rolling all these weeks is also a pain. But yes, somewhere around day 421-431+, theoretically, you can finish the map. But I think I'll save it for later.

Regarding the arrangements for the bug - I used only 2 configurations.
Ballista + any non-flying unit + 5 snakes. On the Hydras, I took 4 snakes, leaving the possibility to attack the ballista from below - judging by the HP, it was hit once or twice, but then the Hydra standing right next to it somehow didn't attack it.
Wagon + lizards + 3 dragonflies. Against Thunderbirds and Griffins, all this was covered by 1-level Goblins - it all worked out well.
It seems intuitively clear how to arrange the units here.
In SoD_SP, Ctrl+Z only allows you to defend for 1 round, I don't think this is compatible with the quick battle bug
