Instance Crash: Offset Chilled Ground Instances + Navira's Oasis

This issue remains unresolved as of 0.4.0b Hotfix 2.
--------------------------------------------------


Previously titled Instance Crash: Trail of Ice Companion + Navira's Oasis


Bug Description
----------------------
The instance crashes and disconnects the player when the player uses Command: Navira's Oasis on multiple Chilled Ground instances that are not in the same position and/or are not the same size. This does not occur 100% of the time. It appears that the bug is linked to the area instance itself, as on some area instances the interaction is able to be completed successfully any number of times, while on other instances the interaction immediately crashes on the first attempt.

Tamed beast companions and monsters with the Trail of Ice modifier create multiple instances of Chilled Ground, so using Command: Navira's Oasis on these can also trigger an instance crash.


Expected Behavior
----------------------
1. Both instances of Chilled Ground are converted into Navira's Oasis. This is the behavior that can be observed when the bug does not occur, as shown in the 4th & 5th videos listed above
(https://youtu.be/rtPNlq-Twk0 & https://youtu.be/QrD5hvw8JWY).
3. The instance does not crash.
4. The player is not disconnected from the server.


Steps to Reproduce the Bug
----------------------
1. Use Frost Bomb twice to collect two Cold Infusions.
2. Use empowered Ice Nova, move a short distance, and use empowered Ice Nova again.
3. Use Command: Navira's Oasis while near both instances of Chilled Ground.
5. Instance crashes and you are disconnected from the server.


Context
----------------------
I want to use the Navira's Oasis skill. It's a great skill and looks pretty when it works, but can crash the instance if there is more than one chilled ground nearby, whether the ground is produced by the player, an ally, or an enemy. This disconnects all players in the instance, not just the one who used the skill.


Videos of the Bug
----------------------
1 - https://youtu.be/ez-84tPE4vU - The instance crashed when attempting to use Navira's Oasis on Chilled Ground produced by a tamed beast companion with the Trail of Ice modifier.

2 - https://youtu.be/oYC_AJ8MJkM - At the start of the video you can see a Navira's Oasis that had been successfully created from a single instance of Chilled Ground. Then the instance crashes when trying to create a Navira's Oasis with two positionally offset instances of Chilled Ground.

3 - https://youtu.be/yf40_SNA9MQ - Navira's Oasis is successfully created from two instances of Chilled Ground that were created in the same position. Then the instance crashes when trying to create a Navira's Oasis with two positionally offset instances of Chilled Ground.

4 - https://youtu.be/rtPNlq-Twk0 - The instance crash bug did not occur with Chilled Ground from Ice Novas. Tested with two instances of Chilled Ground in different sizes and two instances of Chilled Ground in different locations. In each case, each instance of Chilled Ground is converted into its own instance of Navira's Oasis. Hoping that the bug was hotfixed while I wrote this report, I tried using Navira's Oasis on Chilled Ground from a tamed beast companion with Trail of Ice, but the instance crashed.

5 - https://youtu.be/QrD5hvw8JWY - The instance crash did not occur when using Navira's Oasis on an enemy monster with the Trail of Ice modifier. Even with the addition of player-created Chilled Ground (from empowered Ice Nova) or a beast companion with the Trail of Ice modifier, the bug still did not occur. However, after switching area instances, the bug occurred again when attempting to cast Navira's Oasis on two Chilled Ground effects from empowered Ice Novas.
