What version of Somnia Awoken are you using?
Somnia Awoken 1.16.4-2.0.1
Minecraft 1.16.5
Forge version 36.1.2

Describe the bug
After a crash (specifically a ticking entity exception, I noticed) Somnia seems to treat the approximate in-game time of the crash as the new default "noon" as if the world were freshly created at that time. This results in an incorrect wake-up time when sleeping normally or using the clock to select a wakeup time, such as choosing 19:00 with the clock waking the player up shortly before 6:00, and sleeping in a bed at roughly 20:00 waking the player up at nearly 17:00 in-game time.

Is this bug related to another mod?
No

To Reproduce
Steps to reproduce the bug:

1. Create world with Somnia installed and allow time to run for a period of time, preferably towards night
2. Induce a crash caused by a ticking entity exception
3. Load world and sleep by choosing a wake up time
4. Wake up time and chosen sleep time will be desynced

Expected behavior
Wake up time and in game time stay synced at all times

Additional context
On a side note, I also experienced this on the 1.12.2-1.10.2 version as well. Also, no other crash types seem to cause this issue that I have experienced thus far.
