I place a factory requester chest and it doesn't pull factory buildings. Tried hitting R (the key it says to use in game) over it while placed, before placing, while holding it over a factory building, nadda. I've read the FAQs.

Ah, this seems to have broken back when requester chests stopped having a maximum number of requests. Thanks for reporting!

It's now fixed in version 2.5.3.

Works like a beauty now, thank you! Question, is the page thing from when chests had limited requests?

Ah, it seems I forgot to update the description text. Yeah, there are no more pages and the requester chest will just display all currently unplaced factory buildings.

I tried hitting R, seems like that did update the requests. Handy, do keep it as a feature!
