tldr; asia has been buggy for ages, sometimes save char data gets out of sync with the state of the on/off season.
I started this season on asia with 91 paragon and 2mil gold. I also guessed it would happen.
last season I decided to try and complete the season journey in all the regions (Im in NZ so my ping is poor to all of them anyway). I noticed that asia servers always showed me the same Challenge Rift week after week. People suggested logging in and out until you would see the correct CR, this didnt work but what I did notice was that sometimes when I would login I would have 0 paragon (instead of the 800ish I had). I had everything I was wearing and anything in the inventory but the stash was empty. I would switch between classes and log in and out, they would all be 0 paragon. So I played a few rifts, logged in and out and my 800 paragon was back, anything I had from those few rifts was gone. This happened a lot over the end of the season and non season. Every now and then Id get the wierd low paragon back, it eventually built up to 91 paragon and a few mil in gold.
It was like how your stuff is handled after season end, you have stuff you are wearing but not in your stash (that you have to claim via mail). This felt was like I was sometimes logging into a user profile server that wasnt in sync with the rest of the region, it didnt know what para I had or what my stash was. There were other issues on asia too, most of the time you couldnt load the ‘shop’ to get pets equipped etc, or the game would give random errors when launching.
At the start of this week the asia Challenge Rift finally changed, ping improved and a lot of errors went away. However once the season started, the seasonal monk I created had 91 paragon and I knew the issue was back. Given that previously sometimes I would eventually revert to the correct paragon I didnt want to see that happen during the hard work of season start, so I just kept logging in and out of D3 and remaking a new monk in the hope of seeing 0 paragon, but it was always 91 para. So I caved and played the season, but I didnt do the CR as that had never worked for me, or it had never given me the reward. Dumping the para I had in movement speed and resource reduction helped, the 2 mil gold got town leveled up and some crafting done. I got lucky in finding crudest boots and leroics helm on the way so it didnt take too long to get to 70. I got 2 shards from kulle, 1 from a random chest, and 1 from an elite, so the rubies helped too, though the drop rate is far less than some youtubers would have you believe.
After I hit 70 I gave the CR a shot and for the first time on asia it actually worked and I received the reward.
I’m going to guess everyone else is similar, If you had a previous season or off season that was loaded in this weird way, when you made a new character this season it just continued the same thing of thinking you were already underway with whatever paragon and gear it thought you had, especially if you rebirthed.
Anyway, I’m confident, the issue is in asia only as Ive never experienced it on US or europe. Im also confident the blizzard team will eventually resolve it, but it will be interesting to see if they restart the asia season or not, right now, nobody is competing on even ground.
