Match Five Water with Seed Fails Collect

Where is the rule written that water/seed swap should disable the five-collect? It does not seem logical to me. I think it should. Perhaps it is a bug.

It must be matching because the two pairs on each side are collected. Why penalize multiple actions at once here when that is a fundamental strategy in playing? What does a player expect when making that move? (five in a row fun) When it doesn't happen, what is the player's emotion? (disappointment) What would hurt in making the game fun? What is the benefit of the disappointing way the game handles it now? If the common behavior is not kept, that type of thing should be published in game rules.

@Rancid Think about five cropies ooooo; if the outer four disappear xxoxx then the middle must have been a match xxxxx.

@Rancid, go try it and see that even though the drop disappears the two pairs of cropies beside it are collected. That means it was a match.
