So I noticed the other day when I went to put some bushels on the public market, that there now seems to be a cap on the max bushel sell Price?
I haven't narrowed it down to a specific number just yet, but the max seems to be somewhere between 250 and 275? (based on the fact that I couldn't put my bushels up for 360 initially, and that 250 was a price i COULD put them up for, but 275 was a price I could NOT put them up for.
Was this an intentional change and simply not mentioned in the changeset as it seems to have only started this reset?

I believe military and bushel prices are 3x PM price.

this must be new then, as I now cannot selll on public for above 200.
makes stockpiling ahh less than awesome.

It's not new. Max sell price has been 3x PM since at least Earth Empires started (and I believe Earth2025 days).
I don't play alliance, but what I believe did change this set for alliance was the PM price for bushels. This was adjusted in the most recent change set. So 3x of the "new" PM price would be different than what it was in the past at the old PM price.
