Faults like these have caused 3 other Innogame products to fail before they even made it out of Beta.
Not in the slightest. Bugs are part of any game, even those runs by companies who are twice older and twice richer than Inno. What gets a project closed (those other Inno projects were
closed as far as I'm aware, they didn't fail, there's a difference between the two) is a simple decision where during the testing period the company decides the resources that will be required to finalize and maintain the game for different markets and languages are too great in comparison to the interest shown in the game. To put it in simpler words, they see that the game might not do very successfully so instead of risking a failure they close the project early (or if the game has been around for a while and it feels it has run its course, then they close it since there's little point in keeping it around).
What you see as something bad done by the company is in fact a very smart move from their side. They send out surveys and do analysis of whether or not the players like the game, how much time they're spending on it, what aspects of it they like and what aspects they don't like, and based on all the info they collect they decide whether a project is appealing to the general public and seems promising enough to be continued. What you see and what you can access now (this beta community and the basics of the game) is just the root for a tree. If they see that people are interested in this type of trees, they will let it grow by adding more content and working on even more content (this means hiring more staff, spending more resources), and opening servers and communities for many other markets (this means hiring extra staff, doing translations, spending even more resources). But no, bugs (especially of this small type) have definitely not closed down a whole product.
As for the bugs themselves, they're obviously not pleasant for anyone, but this is beta and they're to be expected. Maybe in the future, as they've done with other products, they will offer premium currency for testing/reporting bugs. Till then, reporting a bug helps you as much as it helps them, because that bug will be fixed and you'll be able to continue playing without that bug.
