Some possible "solutions" (or at least helps).
1) Sell scrolls for a lot less than the "official" value. When I sell them, I sell them for 20% discount. Or did when, as a scrolls boosted player I sold them. I generally don't sell them now because I've adjusted my output so the place where the amounts I have are stable. But selling at a discount will work. You may have to go 25% but if you think about it, there are silk and crystal boosted players and they do need scrolls so they buy scrolls.
2) If you do have any scrolls boosted players have them put their scrolls in storage and use the space more T3 or T1 production. Then cross tier trade with them for the scrolls they need. The point is, it may be cheaper for them to buy scrolls than produce them and the space can help in other areas. I have 9 steel plants and no scrolls because I can trade my surplus of steel for silk and crystal. The idea is to use your space to produce that which has enough value to get you crystal.
3) Find a fs with a suplus of crystal. We did when we needed silk. If they have a shortage of something you produce in abundance, arrange a scheduled trade with them. Then we arranged bi-weekly large trades of 500,000 silk for what we had at the time in surplus -- scrolls, I believe. Now we don't need silk because we've adjusted our methods pretty much balance it. Then we would "send" a member there after tournament, they would pick up the silk and drop off the scrolls. They they'd come back. This was before the Spire so there was time. Not sure how it would work with the Spire unless they start the Spire a bit late.
4) Keep regularly posted something for crystal trades up. We used to put 109,000 ("9" being our note for "foreign" trades to be left for our neighbors). By keeping them up all the time and adjusting the price to make them attractive you will find you get your crystal. When we found we needed crystal (it was crystal at the time) it took a few days before our trades started moving and we built a surplus.
5) Have a surplus. Sounds a bit counter-intuitive but by having a surplus the "hurt" of being short doesn't happen as much. Combined with #4 it works. I keep a surplus of 2 million crystal and silk on hand and seldom does anybody in my fs have a problem with not being able to get those goods. I do this for all the goods and this minimizes the impact of short term shortages. You still have to address the underlying low production problem, but it definitely makes things easier.
Those are my suggestions, some of which others have made, above, of course.
