You can get stuck while gathering a Collectable if you open any window while gathering.

How to reproduce:
1. Find an unspoiled node (ie. Old World Figs)
2. Hit Collect
3. BEFORE the confirmation window pops up asking you if you want to collect it, Open up a window like Timers (/timers)
4. Stuck there unable to cancel gathering until the node disappears

You are not able to move, cancel, collect, return, etc. Any action is void you are stuck in place for the duration of the nodes uptime.
Opening up a window like Timers to remind you what the collectable rating is for a turn-in just straight bugs you in place.
