If **none** of the connections to the transistor are attached to its probably not a problem.
However it is a very bad practice. Could make for some unpredictable behavior with substrate currents and latchup issues.
Depends on layout and if the substrate region is subject to currents.
Ground your substrate out and tie your N-wells up.
