Sustaining the energy field has become easier, but speed fluctuations still cause rapid bubble collapse. Compensation algorithms have made re-establishing the bubble almost instantaneous, but test data suggests that wave fronts form from the collapse which might cause surrounding persons to be shunted from their local dimension to neighboring ones. In cases where dimensional lines and time/event lines cross it seems that persons are swapping from one dimension to another. This phenomena has occurred on a limited number of occasions to date. It should be considered scientifically relevant, but the full significance is not known.
The last test had one interesting data point. It seems that at the moment of a collapse a high energy source was detected in proximity, then vanished. Possibly some sort of drone aircraft or other experimental vehicle which was shunted to an alternate dimension when the field briefly collapsed.
