If you wait a few seconds after you clear out the first section a barge arrives to give you your gold, along with a game message letting you know.
What do you mean with first section? Is it the "Breach" quest? If that so then I still got no log message, idk if there is a barge coming in, I was too busy defending the bases.
I play it on Hard Mode with Reforged V1.36 using the Custom Campaign feature, idk if using Campaign Splitter would be better.
Anyway, here is my experience and review up until the start of 11th mission (I restart some times to check on the bugs so I didnt do anything past building base after Breach quest and defend it from several enemy waves, includes 2 Anubarak's attacks, will continue some time later).
Overall Bugs:
1. When I load my saved file, the exclamation mark in map for any quests will appear again even after the task is done. However, the quest still counted as done. Some of them probably makes a minor bugs on the gameplay, for exampleShadow Weaver aura in the circle of power becomes green after reloading instead of purple (Chapter 4), Respawning enemy/creep like the Tunnelers in the dungeon mission (Chapter 5), for some reason after intercepting NorthEast Grey attack wave in Azjol Nerub gate mission, Anubarak forces stopped coming (Mission 10).
2. Sometimes a saved file cannot be loaded because "it cannot locate the map file" or something like that, as if the map being deleted. Idk if this cause a problem in Optional Quest Reward.
As I said above, I have only finished the 1st quest (Breach) and am still on 2nd Main Quest of the Final Mission, so if there is any rewards that appears later on then idk. Bugs about Rewards in Final Mission (format: Log message received; Implementation (Working or not), in case choices exist, the red one is the one that I chose):
Mission 1 (Get extra 1000 gold): No log; No gold added or barge coming (Not Working)
Mission 2 (
Help Lich or Dreadlord): No log; Lich was there from the start, but the necro and banshee only produced after Breach is done and there were still some Aboms, Crypt Fiends, and Obsidians at my base but probably that was only the initial forces (Working).
Mission 3 (
Destroy Land Forces or Air Forces): No log; Visually there is almost none of the Nerubian Undertakers up until now. (Working)
Mission 4 (
Get Orb or Frost Wyrm): No log because I chose the Orb; The undead ally build a Boneyard but up until now I do not see any Frost Wyrms. (Maybe Working)
Mission 5 (Kill Troll Warlords): Log exists before the Breach quest; Unfortunately no Undead troll at all. (Not Working)
Mission 6 (Weaken Hadronox): No log yet cos I am pretty sure Hadronox will be in later point of the campaign; Even if it works, idk the Hadronox supposed to be at what stats originally, so I guess there is no way to know directly. (Idk yet)
Mission 7 (Collect Corpses): Log exists; Log exist also on the Mission 7 for faceless ones and also the rest of the campaign for the nerubian (Mission 10 & 11), but 10% difference is not really discernible right away. (Pretty sure it is Working)
Mission 8 (Extra time for Safe Passage): Log exists; I get 2 strikers and 1 corruptor, but I got no original starting forces except 4 apostates and 1 monitor so boy it will be hard without them lol. (Working)
Mission 9 (
Get Attack or Defense Upgrade): Log exists; It starts with level 1 of both attack upgrades. (Working)
Mission 10 (Defense Crypts): Log exists at the start of the mission; I defended 4 crypts but I have not destroyed the Nerubian Preservers and Pit Broods yet so I guess the spawned reinforcements is not coming until they are destroyed, right?. (Idk yet)
