description of error

I am wondering why so many strange things are happening to my project, especially things I cannot reproduce in a new blend file. I am reporting this so you can take blender's memory management (assumed) into consideration regarding the BGE. I don't want to waste your time with reports you can't fix. I realize that trying to debug/trouble shoot these types of problems is very difficult, is random, and could be caused by any thing. One thing I have noticed, strange things happen when removing logic bricks after running the BGE for a while (could be a coincidence). Although I am just a amateur programmer, I am experienced enough to know that strange things happen when pointers go bad, or when memory is mismanaged (not freed properly, or get mixed with other memory).

I was testing my project "Block Breaker" by playing it in the viewport, stopping and stopping the BGE, etc... The moment I take out a logic brick: boom! something strange happens (again). This time some text curves just would not render. After a test telling me where they might be, they are in the same place, just not being rendered, not even in wireframe mode, while the BGE is running. Lucky for me, when I closed then reopened blender, the problem went away. This makes me wonder if something funny is going on in the memory management (or the memory hardware, who knows).

I am having another strange issue where the animation on a object is being played when another animation is triggered. I am not able to reproduce the bug in a new blender file; but, it remains in my "Block Breaker" project. When a collision occurs on a certain object, it will tell the surrounding objects (a instance of a group of objects) to play a animation then delete from the scene. This works, but with a side effect. The object receiving the collision also plays its own animation, or so it seems (it looks a bit different, but it still is a similar animation). If I take out the animation from this object, then nothing happens on this object. If I borrow a animation from another object, it still plays when it isn't supposed to. This does not happen if I set the Physics type to static or call the function suspendDynamics(). I have carefully stepped though all the logic bricks and code and cannot find the problem. I want to send you my project; however, the size limitation prevents me from attaching it here. If you have a preferred alternate method for sending project files, please let me know.

If you get a lot of unpredictable bugs it could be faulty memory.

Try run a memory checking tool such as: http://www.memtest.org

No clear steps to reproduce, no simple file demonstrating the problem, and the description is unclear as to what the problem is. Also, a more descriptive title would also be nice.
