CD4511 BCD to 7-segment driver not updating

Using CD4511 IC, the display is no longer updating when the inputs change. This seems to have been introduced between 0.4.14-RC1 and 0.4.14-RC2. 0.5.15 is missing file CD4511.simu so cannot test there.

See attached .simu file for example, basic second counter that works in 0.4.14-RC1 and below but not in later versions.

This is under x64 Linux, have not tested on other platforms.

There is always the option that I'm doing something stupid of course, I'm a beginner at this but really impressed with SimulIDE as an experimentation platform.

EDIT: I see the CD4511 subcircuit is referencing an eLatchD and there are some changes in latchd.{cpp,h} and e-latch_d.{cpp,h} between RC1 and RC2. Might be related?
