Help Entities Package Compatability

[SuikaSukiyo]

I am getting a few errors when trying to use Obi in a project with Entities.

Assets\Obi\Scripts\Common\Backends\Burst\DataStructures\NativeMultilevelGrid.cs(34,13): error CS0305: Using the generic type 'UnsafeList<T>' requires 1 type arguments

Assets\Obi\Scripts\Common\Backends\Burst\DataStructures\NativeMultilevelGrid.cs(88,36): error CS8377: The type 'NativeMultilevelGrid<T>.Cell<T>' must be a non-nullable value type, along with all fields at any level of nesting, in order to use it as parameter 'T' in the generic type or method 'NativeList<T>'

Assets\Obi\Scripts\Common\Backends\Burst\Solver\DequeueIntoArrayJob.cs(12,31): error CS8377: The type 'T' must be a non-nullable value type, along with all fields at any level of nesting, in order to use it as parameter 'T' in the generic type or method 'NativeQueue<T>'

My guess is that it's the experimental Collections package (2.1.0-pre.2) causing it.

How can I fix this?
