Occurring multiple times each day in 2017.1.0f3. Never saw before that. However, I am getting much better about saving my scene every time before I run. 8^)

Oops, forgot the details: 2017.1.0f3 running on OsX, latest mac book pro... Seem to happen regardless of size and nature of the project I have loaded, and so far it has always happened when pressing play (I only have one instance running).

This is happening about 3-4 times a day. This is ridiculous.
