In regard to Work_Bane's bug post, I have also seen strange behavior with the interactions between the Mini Howitzer, Pressor Beam and Tractor Beam option cards. Besides the issues that he raised, if the options are fired at the same bot from different angles, the target bot sometimes moves in strange directions (i.e., not a cummulative effect of the actual option cards).
There is also some potential rules ambiguity here that seldom (if ever) comes up such as:
1. What if a bot is hit by pressor beam and tractor beam from opposite sides? Should the bot be moved 2 spaces (or just 1 space VERY QUICKLY)?
2. What if a bot is hit by pressor beam and tractor beam at 90 degree angles (which theoretically should move the bot diagonally), but there is another bot already in that spot?
Because it is very difficult to reproduce these kinds of combinations (since obtaining specific option cards is not controllable to the average user), it is hard to actually run different scenarios.
