Why was this game removed from alpha with such pervasive game-breaking bugs remaining?

[Patrick of the Isles]

Several months ago, when first testing Ultimate Railroads, I noticed that players could use the opposing players' maintenance cars. I reported the problem, and eventually went back to playing the normal Russian Railroads implementation because of how game-breaking this issue was. In the intervening months, the bug report was closed as fixed multiple times, for instance here:

https://boardgamearena.com/bug?id=51917
https://boardgamearena.com/bug?id=51799

So I decided to give Ultimate Railroads another chance. But my first game back today I quickly found that IT IS NOT FIXED. The players continue to be able to score the opposing players' maintenance cars.

From today: Move 99 of https://boardgamearena.com/gamereview?table=250182171

Using an opponent's piece is such a fundamentally game-breaking bug that I do not understand why this game was taken out of alpha/beta testing. It just frustrates the player to get so far into a game and have the same bug that has been reported and closed multiple times reoccur. A player expects this when testing alpha games, but shouldn't one wait to release it officially out of alpha/beta at least until it isn't possible to use the opponents' pieces?

I would like to have an answer to this question as well.

As much as I like the game on BGA, my opponent today used 2 of my wagons for an additional bonus tile and an additional end game scoring card. It's pretty hard to win that way.

So this is an obvious error in the BGA implementation and clearly players are abusing it. A response here about acknowledging this error and a statement about fixing it would be highly appreciated.

I spoke with the developer about the wagon bug, and apparently it should be fixed now.
