I am level 48 Axton in TVHM and on entering the Cauistic Caverns I noticed that things were noticeably different from around 12 previous visits. On attacking Blue things started OK but when his health was around 25% down it regenerates to around 75%, every time. But the big difference is that from the first regeneration of Blue’s health the beast has been attacking me from underground with only small parts of the Critical Hit zone present. With these you kill off one Critical zone and another seems to regenerate there must have been around 10 Critical hit zones. Another point to note is that no little guys were generated during my 4 or 5 battles with Blue. Help … is this a bug? Advice appreciated.
