System Information
Operating system: Ubuntu 18.04
Graphics card: irrelevant

Blender Version
Broken: 2.83 Beta 8cb10c124e 17 Apr 2020

Short description of error
Under cache type "Modular" (which was the standard workflow in 2.82) resuming a simulation forgets all effectors.

Exact steps for others to reproduce the error

Note: because of #75850 the order of operation here is fundamental to reproduce

Default file. (Activate X-Ray)
Default cube: Add: Fluid > Effector
Add Plane. Move up Z +2.
Add: Fluid > Flow > Type Liquid; Flow Source > Is Planar
Add new cube at origin. Scale up by 2.5.
Add: Fluid > Domain > Type Liquid
Cache type: Modular. Frame end: 10
Bake Data
- The effector is correclty taken into account
Cache frame end: increase to 20
Resume
- The effector is ignored from frame 11 onwards

Note

This is probably related to #75850.

Both bugs make the Liquid simulation totally unusable in a interactive way.
