Hi propmaster, can you show which area I should zoom into to see the problem?

Also if you remember how that area was drawn and could repeat the steps that would help me to figure out what's going on there.

Sometimes it may be better to turn off some of the snaps if they are getting in your way.

For example maybe it's possible you're getting a "tangent to" or "perpendicular to" snap kicking in and you're targeting that instead of an "end" point which is what you really needed. It's good to pay attention to what the snap label says to make sure you're getting the right kind of snap.
