+## Next Level XP workaround
+Beginning at level 40 the xp value shown on the character sheet after "Next Level:" is incorrect.
+This can be worked around with, with a tlk override for the strref 315 "Next Level" that also pushes the xp value out of view by use of a new line `\n`.
+With NWNX this can be done per player and can show the actual value of xp needed for the next level so that it looks as usual.
+```c
+// Todo: Do something to get the PC object as oPC.
+int nLevel = GetHitDice(oPC);
+if (nLevel < 40)
+{
+  // In case of a level down the override might not be needed anymore.
+  NWNX_Player_SetTlkOverride(oPC, 315, "");
+}
+else
+{
+  string sNextLevel = IntToString((nLevel + 1) * nLevel * 500);
+  // The line above assumes you followed the same pattern of xp progression as the first 40 levels.
+  // If not, read from exptable.2da or do what you have to do to get the correct xp value for the next level.
+  NWNX_Player_SetTlkOverride(oPC, 315, "Next Level: " + sNextLevel + "\n");
+}
+```
+Code like the above could for example be run in the base game events `EVENT_SCRIPT_MODULE_ON_CLIENT_ENTER`, `EVENT_SCRIPT_MODULE_ON_PLAYER_LEVEL_UP` and the NWNX event `NWNX_ON_LEVEL_DOWN_AFTER`.
+An alternative would be the nwnx event before opening the character sheet `NWNX_ON_CHARACTER_SHEET_OPEN_BEFORE`.
