fabric-19w07a.6-0.3.6.107
GatewaySummoners-v1.6.1.zip pure SURVIVAL
first of all -> great mod-pack

issue : using the gateway on long distances ( i guess more than 1000 blocks)
MANSION and END-PORTAL are this far away normally

you will land on an Y offest off ca -8
that means , you will land exactly 8 blocks UNDER to rod ( bloody dork and sufficating)
using tp @p x y z you will land exactly at the rod .
at the moment i just build a romm and some stairs
best regards
