Reopening #8384 - Adventure Mode main quest Flower Fetching bug

**Describe the bug**
#8384 was closed for inactivity but is still not fixed.

Flower Fetching quest becomes impossible to progress if you have already picked up the flowers.

**To Reproduce**
Steps to reproduce the behavior:
1. Gather the flowers in the frozen cave before accepting the quest to do so and grab the flowers
2. Return to the cave after accepting the quest
3. The exterior map has reset, but the interior one has not and the flowers cannot be picked up again
4. It's now impossible to progress in the main quest

**Expected behavior**
Either the flowers should be unable to be picked up before the quest is accepted, or the quest should detect their presence and automatically progress to the next step.

**Desktop (please complete the following information):**
- OS: Windows 11
- Version: 2.0.07-SNAPSHOT-11.09

**Additional context**
I couldn't directly reopen the issue without permissions so hopefully this is acceptable.
