Hotfix: The Eternal Bug-hunting Quest (Patreon)

Hi guys! As I mentioned yesterday, here is the hotfix. The two bugs (actually, I think there was a third one, but I forgot to write it down) here are annoying enough that I figured an update was necessary. All the unfinished content for the next release that I added so far should be sealed off and inaccessible, but do let me know if something unusual pops up.

These are the bugfixes:

• Fixed issue with "Does a Barrel Roll?" quest (after moving its beginning to chapter 4, a few visual issues appeared, like a balloon appearing in chapter 3);
• Fixed weird interaction between two quests ("Tree Sap Trap" would mess with "Climb, Check, Come back" if started later, going as far as to render some characters inaccessible);

Perhaps this wasn't necessary, but I feel like it's better to get this kind of issues out of the way ASAP.
