Short description of error

Using domain for fluids in liquid mode does not update replay cache (doesnt free up the cache upon changing sim conditions).

User has to change the domain properties to force caching for replay to be up to date (according to new sim conditions)

Exact steps for others to reproduce the error

Create or use Box primitive
Change it to fluid domain (Liquid mode)
Create icosphere and set it to flow object (liquid mode) place it accordingly into domain
hit playback btn...sim starts and caches for playback (default settings)
Go to first frame and change position or/and scale of Flow icosphere
Hit Playback
Still old sim replay playing even after changing POS or and Scale of the flow object.
Change some properties of the domain object and now the cache starts to be update and is valid for new conditions.

The replay cache should be recalculated or free up immedeately after some conditions changes...imho
