attached screenshot of an inscriber with 57k / 3k RF this will continue with seemingly no limit consuming around 800RF/tick earlier I had one up to 226 MRF : 0

this is on The 1.7.10 pack (modpack on Technic Launcher) runner AE 2 rv3-beta6

Update: it seems that this only occurs with Galacticraft's Aluminum Wire

If it is just limited to a single cable of another mod, it is most likely an issue on their side.
