He is active in Telegram, but not with the name LimxDev. Search for "Chris In Crypto we trust", thats LimxDev. His last post in the german BitSend Channel is only some hours old.

Der Core ist in Entwicklung leider ist die aktuelle neue Version noch nicht fertig.
Translation: The core is in development, unfortunately the new version is not ready yet. Yes, I see him in German BitSend Telegram Channel, but why he is not active in English Telegram Channel?
I thought joshafest is LimxDev because Lucas tagged him when someone asking about LimxDev.
I'm afraid I can't answer your questions either, but Chris answered your questions with his post above.
