Mod did it wrong thus resulting in the bug not reproduced. Follow reporter instructions more carefully and turn on mentioned portal farm instead of creating your own circuit as this bug will not occur without lighting those portals. Mod also mentioned large portal farms cause lag in visual and audio. However, visual and audio lag is not what the reporter encountered. What happened is that the portal farm generates pending tick lag, causing dispensers and droppers not working as expected in earlier versions.
