ID:188021 Incremental compilation encountered a problem with optimized reuse of the previous compilation results -- retrying using normal preservation of the previous compilation results

CAUSE: The Fitter encountered a problem while performing a compilation time optimization that is automatically activated for small design changes. This compilation time optimization can cause a small area penalty because the optimization disables the sharing of physical resources between preserved and recompiled logic.

ACTION: No action is required. The Fitter will automatically retry with the optimization disabled. You can disable the optimization by adding the ENABLE_ACCELERATED_INCREMENTAL_COMPILE OFF assignment to the Quartus Prime Settings File (.qsf) of the design.
