Dungeon Reward Tokens for Multiple Characters
Yes, this. I believe it was explicitly mentioned before that only the gold reward was going to be once per path per day, and that there would be no diminishing returns for tokens.

Experienced this issue too. First run on an ALT is not awarding the full 60 tokens.
Running a path again for the first time with a different character has always yielded full rewards. The bonus daily coin was supposed to be once per account, but all other rewards were to stay the same.
