Step crack issue

Hi,

I purchased an older home (over 100 years) back in January and when I bought it, the previous owner had gutted and renovated it. There was a rather large step crack in the front of the house that ran from the foundation up to about 4 feet above the foundation into the brick. I had that repaired about 2 months ago but recently I noticed the crack beginning to reappear in the same spot. I thought I might have foundation issues that need to be addressed but I also was wondering about something else that could be causing this ...

When the home was renovated he put in a secondary i-beam in the basement about 2 feet away from the original beam for additional support seeing as how the original beam is so old. I notice that where that beam is there is a high point in the floor above. A very obvious one and the floor slopes away quite a bit from either side of where that new beam is located. Funny enough, if you follow the beam out to the wall that's exactly where the step crack is. So what I'm wondering is can it be possible that the beam is positioned too high causing stress at that point which could be causing the step crack? The beam is supported by adjustable metal support poles so I thought that if I could turn the nut a few times on the support poles and lower the beam a small amount if that might relieve the stress as well as get rid of the high point on the floor above. Is it possible that could be the cause?

Thanks
