When using a DM and applying force via blueprints with event tick will cause a crash.
Workaround: Using a timer instead will not cause any crash even with very low values.
Crashreporter: [Link Removed]
1. Open UE4
2. Create a DM
3. Place it in the level and get reference to it in the Level BP
4. Apply Force (no values needed)
5. PIE
Results: Editor will crash when applying force on tick to DM
Expected: Editor should not crash when applying force.
