Port of Aiora Treasure Hunt

[Aloeth Bowstringer]

Last night I be havin' an issue that I shoulda posted last night. I used about 56 turns ta build up me Treasure Hunt's port Max. The first message I got I forgot to copy/paste, but my port max went down about 7mil. The second and further times, I be gettin' this message:
You asked the port locals spending 8 turns.
Your port maximum treasure has been increased by 0.
I be a regular at attemptin' ta find NPC treasure, gettin' me a mil at a time, give or take. But this time I be attemptin' ta go big on a PC. In tha process of savin' up a ton 'o' turns and was tryin ta raise my port max ta raise my PC max.

Your port maximum treasure has been increased by 0.

That means you reached the max at that port and you cannot increase it any further.
