(Just for completeness) The hints at 114GeV in LEP were very subtle and have since been shown to be a statistical fluctuation (which is unsurprising). The Large Hadron Collider (LHC) has observed the Higgs boson at 125GeV. This mass is too high for LEP to have ever seen without further upgrades to boost it's energy and there was no reason to expect it to be as close as it is to the LEP energy. It could easily have been 200GeV+ and well outside of LEP's capabilities. The advantage of the LHC is that is was capable of much higher energies due to being a proton collider (currently 13000GeV), though this comes at the cost of being "messier" to analyse the data. Additionally, continuing to run LEP to check would have further delayed the LHC which would have been very expensive.
