It is a general modular bug that when the creature dies it will ask you to target an artifact creature even when there isn't any and you can put the counters to non artifact creatures if you cancel the game crashes.

General: Nebuchadnezzar
Cards: Star Compass
Error: artifacts that produce mana of any color are supposed to be legal in any deck, even if mana that does not match general's colors has to be considered colorless.

General: any
Cards: Fellwar Stone
Error: as above

confirmed, and counters are not hidden because permanent targeted are destroyed too with the 2nd ability

confirmed, AI side is not affected but player side doesn't have the target choice nor the effect triggering

confirmed, no trigger at all even with the same card cast twice

confirmed

I can confirm with your savegame, however I couldn't reproduce it in another game, even with Disciple of the Vault, must be another interaction

General: Rayne, Academy Chancellor
Cards: Gaea's Cradle, Tree of Tales.
Error: even if those lands produce green mana, it is not forbidden to add them in the deck. They should just provide colorless mana.

This is illegal as the rule is :
A card's colour identity is its colour plus the colour of any mana symbols in the card's rules text. A card's colour identity is established before the game begins, and cannot be changed by game effects.
The Commander's colour identity restricts what cards may appear in the deck.

the rule you are referring :
A deck may not generate mana outside its colours. If an effect would generate mana of an illegal colour, it generates colourless mana instead.

Has to do with cards like Fellwar Stone not cards that have the mana symbol of mana that is not one of the Generals identity.

Ok, so that was really my fault. What about the others?

Which card did behave improperly ?

What exactly should be the correct behavior/interaction ?
Wolfir Avenger triggers Renegerate when it would be put to the graveyard through damage or destroy cards.

Are any other cards possibly affected by this bug ?
