Update about the collars and the updater:
As I mentioned before, I released an updater in the box of the collars that is humm... updated.
Well, it turns out that updater will break the collars!, so I removed it from the shop for now until I discover what's going on exactly. But fret not, I also upgraded the collars with the latest (working) RLV system, so for now the collars I have on the shop are the most updated ones that work.
When and if I have news about the collars I'll let you know. For now just get the latest and fixed-est copy from the shop, and don't try and update to 7.0.1 it'll break your collar.
