Summary	07436: benberob: Unreasonable phenomenon in the game
Description	The problem that has existed since the beginning. In pattern 2, the gas explosion is a miss for the player one floor below. Similarly, a gas explosion on the bottom floor will be a miss for the player on the top floor. In Pattern 3, fireballs that sometimes fall from above may stay in the middle of the floor, making it impossible for players to move forward.
Steps To Reproduce	It happens almost every time during gameplay.

Wd'd like to get actual snapshots from MAME and a recorded .inp file as well in a gameplay detailing the issues you describe. Your screens you are showing in the .png file you uploaded is post-processed and it cannot be determined which version on MAME they were created with, or even if they are PCB snapshots. MAME 0.214 was just released, so please make fresh snapshots with this version (without modification) and describe your issue in text in the report. We also need to prove that such behavior does not happen on original arcade hardware.
