Mission "Living Space" (RU_08_02_DRAIN_DRY) to complete it, it needs two CargoContainerSmall to craft two cabins, however on the course of this mission, it spawns two CargoContainerLarge instead, making it impossible to finish in legitimate way.

What is needed on the course of the mission:

What is spawned:
CargoContainerLarge needs to be replaced with CargoContainerSmall (please for the god of love, don't fuck this up and change things vice versa)

Mission "Like Hot Potatoes" (RU_08_02_GMO_POTATO_BUYING) is unlocked and available to start before mission "Experimental Field" (RU_08_02_FARMING) is completed, however the former mission requires cargo produced by the latter mission, and I've seen enough complains and confusions on reddit about it already.
To fix it, RU_08_02_GMO_POTATO_BUYING simply needs to have its blockerObjectives changed, either by replacing current (RU_08_01_FARMING_FIELD_TUTORIAL) one to RU_08_02_FARMING or by adding RU_08_02_FARMING after that.

Lastly, region requires total of 6 Packed Sand cargo delivered on the course of missions "Supplies for Village" (RU_08_01_VILLAGE_RENOVATION) and "Clean Energy" (RU_08_01_WIND_POWER) and it provides exactly 6 Packed Sand cargo via RU_08_01_FACTORY_WEREHOUSE, however if player fails to preserve the limited amount of cargo, they are locked out of progression, since there's no way to acquire more sand, an infinite sand storage is limited, or the sand should be provided by the respective missions in required amounts.

One small thing but important nonetheless is that the Wind Blade been renamed to "Assembled rocket" in the line 6738, while it should not! additionally, the used trailer here semitrailer_wind_blade.xml does not have unique internal name and reused the one from semitrailer_rocket.xml You can fix that by changing that one string of WIND_BLADE back to "Fan Blade" as it was before the update and by navigating to \initial.pak[media]\_dlc\ru_08\classes\trucks\trailers\semitrailer_wind_blade.xml to add custom internal name for related strings.
but if you'd ask me, I'd change it to Wind Turbine Blade, just saing

Important one, I forgot about it, Glades has none of ZonePropertyResupplyRepairParts for Hard Mode, add at least one, anywhere.

UPDATE:

The limited sandbags problem for the "Supplies for Village" and "Clean Energy" missions has been fixed with the PTS 26/01 update, as shown below:

The other problems mentioned are not fixed and still remain problematic.

Thanks for nakedDave on the discord for noticing it

UPDATE:

The large containers problem for the "Living Space" mission has been fixed with the PTS 02/02 update. It spawns small containers instead of large ones now, as shown below:

The other problems, apart from the sandbags, which were already fixed previously, remain.
