I can't reproduce this bug in last 2.8 build. @Lucas Boutrot (thornydre) : Could you check with last buildbot from here: https://builder.blender.org/download/ and close the task (add action > change status) if this is working for you?
(changing objects selection state stops the cache from being created but the sims keeps running. I guess this is normal as the possibility to move selected objects during simulation has to be supported)

Note:

In fact I have warnings in the console:

'OBSuzanne.POINT_CACHE_RESET()' depends on 'OBSuzanne.TRANSFORM_SIMULATION_INIT()' through 'Transform Simulation -> Point Cache'
