looking forward to seeing this mod updated to 0.16?

Now I know the problem I have put in a work around.
Thanks

running version 0.15.30

The arithmetic combinator cant multiply properly. It can multiply properly with other ores from what I cant test, just seem to get this behaviour for copper. It works for some numbers but not others strangely enough. The number seems to roll into the negative without reason. Picture below says it all.
