(Pond Map) Unable to progress, Zero Action allowed after a certain in game progression

[Description]
After playing the Pond-Map, after a certain amount of time, and collecting 43 resource cards, using 15 roads, the system does not allow the User to progress in purchasing dev cards, or any actions. No win condition are met and the current User is forced to pass all future turns to opponents.

[Setup]
-- Pond Map
-- 3 Players
-- Win Condition = 15 VP

[Actual Results]
User actions are all inoperable. Unable to play Robber. Unable to Buy cards, used all Roads, can't buy or use anything. Trades not allowed for large sums of resources.

[Expected Results]
Is there one? If User met exceeded all limits of the game, therefore is that considered an "Auto-Win" even though the 15 VP requirement was not met?

[Note]
1. All 15 roads were used, but not in sequential order to garner longest 15-road streak (zero additional roads available).
2. Should the "Pond Map" be enforced with 4 players rule to help limit this break in the map.
3. User noted that was blocked = "dococt".
