Since v4-2-3 I haven't had any errors yet and I have been playing for hours a day for the past few days. I did update to 4-2-5 when it was released and played for an hour and a half through a 7 day horde with no errors. So far it looks like great fun and I am enjoying playing it. For my own enjoyment, I edited the entityclasses.xml to allow the corpses to stay around longer so I had time to loot them after the 7 day horde night.
I did find something strange, drinking green tea does not give the empty jar back. I looked at the xml in items.xml and found that it didn't contain the code to give the jar back. Green tea starts at line 13505 and just needs the line "<property name="Create_item" value="emptyJar" />" placed in there like the code sample below.
Code:
<item id="1799" name="GreenTea">
<property name="CustomIcon" value="goldenRodTea" />
<property name="CustomIconTint" value="008000" />
<property name="Meshfile" value="Items/Food/goldenrod_teaPrefab" />
<property name="Material" value="glass" />
<property name="HoldType" value="3" />
<property name="Stacknumber" value="64" />
<property class="Action1">
<!-- UseAction -->
<property name="Class" value="Eat" />
<property name="Delay" value="1.0" />
<property name="Use_time" value="..." />
