Deeprun Tram quests weird behavior

[ghost]

Current behavior: When Deeprun Tram Roundup is abandoned, player receives item Squirrel Token which starts this quest.
This token is removed when quest is started using it. If player abandons the quest again and they have Squirrel Token, message "You don't have any space in your bags." is always displayed.
If quest is completed, attempting to start it again using Squirrel Token will result in message "You are already on that quest" displayed.
Token also has yellow message "Value Be Ten Silver Coins..." but player cannot sell it.

If player accepts next quest "Me Brother, Nipsy", killing any rat will display a message "Deeprum Rat Roundup failed." once.
If player abandons this quest, another Squirrel Token is given, but this one has twenty coins value and starts "Me Brother, Nipsy".

Expected behavior: No Squirrel Tokens, quest should never fail after it is done.

Steps to reproduce:

1. Go to Deeprun Tram
2. Do the questline, don't forget to abandon each quest
