Issue I453 [70,chargerepulsion,critical,resolved] Modifying ion_charge can cause charge repulsion effects to be wrong. Prior to 8.0.4-TEST19, if a user program modifies the ion_charge variable, then charge repulsion effects (if enabled) may not calculate correctly. This likely affects only beam and Coloumbic repulsion (but not factor repulsion). This is because some charge repulsion variables were being precalculated before the Fly'm and not updated if ion_charge changes. As of 8.0.4-TEST19, it is safe to modify ion_charge (as well as the new ion_cwf variable) when using charge repulsion effects. Affects 7.0. Resolved in 8.0.4-TEST19 (test case t3). Not patched in 7.0.
