ParticleSystem throws Unsupported type MultiModeParameter error when editing after upgrading from 5.5.x
When upgrading project with particle system prefab from 5.5.x to 5.6.x, editing the particle system in 5.6.x throws Unsupported type MultiModeParameter error.
To reproduce:
1.Create new project using Unity 5.5.0f3
2.Create particle system in the hierarchy
3.Make it a prefab
4.Edit particle system settings from the hierarchy(do not press apply)
5.Open the project in Unity 5.6.x
6.Edit particle system in the hierarchy
Expected result: editing with no errors
Actual result: console throws Unsupported type MultiModeParameter error
Reproduced on: 5.6.1f1 5.6.1p1 2017.1.0b5
Notes:
Using text difference program you can see that prefabs created in 5.5.x and 5.6.x has opposite curve values, these values are opposite in all settings.
This is not a regression as the bug happens when upgrading from 5.5.x to 5.6.x.
Tested this on Win 10 and MAC OSX 10.

confirm: Unity 5.6.1
when editing particle system I get this error and particles stop simulating (need to press simulate again).

I can confirm this is an issue, it seems to affect all the particle systems in a scene if the scene was serialized under Unity 5.5. Is there a known fix or workaround to this issue?

Unity 5.6 doesn't read the settings from particle systems made in Unity 5.5 correctly, which means that editing a scene in Unity 5.6 and saving it can result in loss of data. The issue is more serious than just getting an error message when editing the particle system.
