Perfect, thank you Ivan.

Maxim, should we include it in ‘version-1.4.0’?

I’m fine either way (it’s a much welcome fix but it’s not critical IMO).

Is this a world rebuilding change?  If so, I'm afraid it'll have to wait
until the next rebuild cycle comes as we're already far into building
the version-1.4.0 branch.

Thanks,

Maxim
