[2.0.37] [SA] Unable to set up forced drop-off on space platforms

[Hares]

Background

I was experimenting with fast drop-offs: items are being consumed by landing pad in a slow rate, so to not waste time of the platform, I tried automating instant dropping of cargo and didn't succeed.

Steps to Reproduce

1. Have a platform with two request groups for the same item:
   1. Request N to N from planet A
   2. Request -N to -N from planet B
2. Navigate platform to planet A
3. Wait for the request satisfaction
4. Navigate platform to the planet B

Expected:

• All stacks of that item are dropped-off

Actual:
Configuration:

• Item: Cryogenic science pack
• N = 20k (100 stacks)
• Planets: Aquilo -> Nauvis

Result:

• Nothing happens, despite tooltip explicitly states 0 is max allowed value combined from all request groups

•

Also tried different combinations of settings, some didn't have any other effect, some worked partially - like from -2N to 0, which resulted in one drop of 10 stacks upon arrival, and exactly one drop.

May be caused by signed/unsigned int magic.

Update

When the platform receives the delivery, it re-checks trash conditions and drops a new group of 10 stacks. However, this does not happen if a platform re-arrives to the same planet as a new schedule entry, with or without wait condition. (Un)checking "Unload" checkbox does not affect the behaviour as it looks so trashed items are dropped even when unload is not permitted.

I believe the trash conditions are also re-checked when the hub inventory storage changes (an inserter puts an item in; interestingly enough it does not happen when an inserter takes an item out).

So, technically, if I add condition "Nauvis == 3" with to pull & push random trash -- it will work?

Thanks for the report. This is now fixed for the next release.

Also, what would be correct configuration of requests after the patch?
