Graal Classic Bugs

[Zulithe]

So far I have encountered this in two areas, both in Tyhm's Quest (the one with MegaKnight, etc)

In the puzzle room just before the train that contains the blue and red bushes (the red bushes explode when you throw them, the blue ones combust when they come into contact with an explosion) THE BLUE AND RED BUSHES DO NOT APPEAR IN THE LEVEL. I told a GP about my problem, he refreshed the level and it did not fix it. Then he came to the leve I was in, and somehow managed to get the bushes to appear.

But, even though they appeared, once I picked them up and used them, the bushes DID NOT REAPPEAR even after hitting the 'refresh' switch

FINALLY I managed to pass this level and progress... only to encounter the same problem later in the quest

On level tyhmcidliz3.graal There is a boss, and you are REQUIRED to throw red bushes at him (you can't even use your other weapons!!!! WHY!?!?!) Well guess what, NO RED BUSHES, I see where they are supposed to go but they are not there. GPs updated the level, they still did not appear. And so, I can not pass the boss. I am very frustrated.

Please fix this problem. I have seen MANY MANY other problems on Classic, but this one is by far the worst and prevents you from progressing.
