1. I was light farming Tam-Tara Deepcroft (Unsynced) light for Zodiac Weapons
2. After a while i suddenly got system messages for both mentioned times which are
following:

- Unable to register. Maximum number of duties exceeded.
- Unable to register while penalties are being incurred.

3. I couldn't see the cooldown penalty which would normally show up on duty finder and first time this happened yesterday it took over an hour till i was able to queue and today after 2 hours im not still able to queue anywhere.
4. I don't understand why this is happening because i was simply just farming light and didin't cancel the queue just normally exited after every clear.

Is there any way to fix this?
