You can check for hook functions pc->can_insert_card and pc->can_insert_card_into.
First check is card can be used by itself, second check if this card can be inserted to this item

This issue by design. After warp server forgot any npc related things.
Probably need change this. Need talk with other devs. Reset happend in clif_parse_LoadEndAck.
Or better some one create bug on github bug tracker?

If you mean warnings "Unable to set ..." this is mostly ok.
First option useless and may be even not safe, it ignored (SO_REUSEPORT)
Option with TCP_THIN_* need for better latency, look like your hosting not support it.
 
With or without this options all will works.

If you mean buildin variable it should be BaseLevel (without space)

not sure what wrong, try from start.
autoreconf./configure --disable-ltomake lto disabled, because it broken in some gcc versions

try add
 
tick_def = st->luk>249?0:tick_def;

I gave changed line, this mean need remove old "tick_def = 0; //No duration reduction"
