An accidentally disconnected wire caused a requester stop to overfill (since it was only counting the chests for one wagon) and after fixing it I noticed a very strange behavior:

- The requested stop started calling trains as if it was a provider (which of course never loaded since the inserters go the other way and would just time out).
- The station is configured with Iron Plate = -64k, Request Threshold = 32k.
- At the time of this event the chests Iron Plate content was about 160k.


I assume that once -64k+content goes negative again the strange behavior will self-fix itself. Just to be safe I disconnected the wire that goes to the LTN stop lamp and will reconnect it after the chests have drained.

But I am curious. Is this the normal intended behavior? Shouldn't the presence of a Request Threshold in the configuration cause the stop to not even consider acting as a provider?

Request and provide threshold are accounted for separately to allow mixed Provider/Requester stops. Set your Provide threshold to 1M or something like that for pure Requesters. There is also a mod setting for default thresholds. I tend to set both default provide and request thresholds to a few million. That way you have to set a threshold signal for each stop, but you can't have accidents like the one you described.

Makes sense, and thanks for the advice.

Another way you can fix it is to filter what you send to the stop: at a pure provider, send just the inventory using "each > 0 output each" (usually not a problem, but an error in wiring something nearby could cause a provider to turn into a requester). At a pure requester, send just the request by sending "each < 0 output each" after you've added the inventory to the request. The one mildly annoying thing about this way of doing it is that at a requester station, you have to set the config in a separate combinator from the request.
